what is physical description of spruce

age Product Description Baby Blue Eyes Spruce is a conical-shaped, fully branched selection of Colorado Spruce with a uniform growth habit and intense blue needles. On the average it will grow upward about 8 inches per year compared to some Colorado Spruce that can grow as much as 12 to 18 inches upward per year. Since it is a grafted plant , the growth rate can vary depending on the rootstock (understock) that it is grafted on to.

The color may range from dark green to quite blue, but if the needle rolls between your fingers as smoothly as a square wheel, it's a spruce. If you try this with a fir needle, it won't roll at all because it's flat. Like spruce needles, fir needles don't grow in bundles, either. Like spruce trees, fir trees tend to be tall, dark and symmetrical. Like pine trees, some types of fir trees are used for Christmas trees.

Pine Trees or Evergreens?

Pine Trees or Evergreens? Pine Trees or Evergreens? by Don Janssen, Extension Educator Printer-friendly Format All pine trees have needles, but all needled evergreens aren't pine trees any more than all dogs are dachshunds.

Telling pines from firs from spruces isn't any harder than distinguishing beagles from Bassett hounds from bloodhounds -- you just need to know how each one is distinctively different from the others.

A distinguishing trait of pine trees is that their leaves (the needles) are bundled together, usually in packs of two to five. The needles may be long or short or somewhere in between, but if you find needles in bundles, you have a pine tree. If you examine a needle from a tree and find out that it's not round and not flat but rather four-sided, you are looking at a spruce needle.

Pine Trees or Evergreens?

Like fir trees, spruces have single needles connected to the stems. However, spruce tree needles are sharp and square-shaped. On a real tree, spruce needles easily break apart if you bend them. As a whole, spruce trees sport the traditional full Christmas tree shape, thanks to their upturned branches.

Evergreen Everlasting: The Differences between Fir, Spruce, and Pine

Tweet November 24, 2011Jessica | Balsam Hill Designer Holiday Decorating Ideas Evergreen Everlasting: The Differences between Fir, Spruce, and Pine With so many artificial Christmas trees available in the market, it’s difficult to tell each one apart.

How’s a person supposed to tell the difference between a Norwegian Spruce and a Balsam Fir? And often, we want to make sure that our trees look like their Natural namesakes.

Fir, spruce, and pine are three of the most popular Christmas tree varieties and have their own characteristics that make them special.

If you were to look at the real trees, here are some things you would notice. Use these distinguishing characteristics when you shop for artificial Christmas trees, to make sure that yours looks like the real thing: Fir Fir trees have individual flat needles attached to the stem. The needles grow in a spiral on the tip and lay flat, and this kind of display gives fir trees their full look.

Like our BH Balsam Fir, its shape is bushy and full, which doesn’t leave much room for ornaments and is perfect if you like a less-decorated tree. Spruce

Much like our Vermont White Spruce tree, their strong branches can hold heavier ornaments, so load them up with your biggest ornaments with confidence!Pine Unlike the fir and spruce trees, a pine tree has needles that grow in bundles — you can see three to five needles bunched together on a pine tree branch.

Pine trees have fewer branches, so they tend to look sparse with their upturned branches. However, this leaves lots of room to hang ornaments at the back and middle of the branches, allowing you to hang all of your favorite ornaments. Try this decorating tip with our Scotch Pine Tree. With the pointers in mind, you can easily find the perfect Christmas tree!

Sometimes a spruce can be mistaken for a fir, but you can the difference by looking closely at the needles. If the needle is flat, then it is a fir because spruce needles have four sides. Fir tree cones are much softer than pine cones. Pines and firs both are often used for landscaping purposes and shade.

What Is the difference between fir and pine trees?

What Is the difference between fir and pine trees? Biology There are basic differences that exist between pine and fir trees. Some of these differences are botanical name, native ranges and cone shape. They also have different foliage characteristics.

You can tell the difference between the two by focusing on needle clusters and length. Pine trees and fir trees are both conifers that bear cones.

These two trees are also members of the same plant family. There are about 50 fir species that are all native to cold and mountain regions in the Northern Hemisphere. There are about 120 species of pine trees and they are native to many different forests that range from cold regions to the subtropics.

Pines can consist of trees or shrubs. Pine trees have needles that have from 2 to 5 in the clusters. Pine needles are shiny, soft and thin and can range in length from less than an inch to as long as 16 inches.

Fir tree needles are short and they are always less than 2 inches long. This is a very easy way to tell the difference between pine trees and fir trees. Both pines and firs grow tall and upright. At the lower branches, firs are much wider. The bark on a fir tree is smooth and cork-like and it is often hidden by the branches and needles.

The bark on a pine tree is cracked with plate-like scales that are darker in color underneath. A fir tree has cones that can be purple, green or blue. When these cones are ripe, their color changes to a golden, medium brown. Pine trees also have cones, but they are green and when ripe their color changes to red-brown or black.

A white evergreen pine tree can grow to a height of over 100 feet. They are admired for being so tall and beautiful. European settlers used these pines for building log homes. Fir trees can withstand fires due to their thick bark. Firs can be found standing tall and beautiful in the Southern Appalachian Mountains.

During the winter season, these trees are still beautiful while most others have lost their leaves and are bare. Pines and firs will thrive in full sun to partial shade with well drained soil. They are easy to grow. Firs make excellent Christmas trees and are also used for other decorative purposes. Firs are closely related to cedars.

Firs, pines, cedars and spruce trees all have wonderful aromas and they all help to enhance the appearance of the landscape. Pine and spruce trees have wood that is much higher in value than firs. Fir trees do not shed their needles as much as pines.

It is pine trees that date back to ancient times and in ancient folklore the cones were believed to stand as a symbol of fertility. Related posts: Identification and growth of ponderosa pine trees Tree Profiles Table Mountain Pine Tree Profiles Parana Pine Pine Trees Identification and uses Tweet

d.pine, fir, spruce - Pine, fir, and spruce are quite different from each other, though they are allconifers; pine has clusters of long, needle-shaped leaves, spruce is a type of fir, and the onlyscientific difference between the two is that spruces have rectangular needles while firs have flat,needle-shaped leaves.

While the majority of these coniferous tree species have a fairly unremarkable average growth rate (between 6 inches and 11 inches per year), the Sitka spruce (Picea sitchensis), Norway spruce (Picea abies) and Colorado blue spruce (Picea pungens glauca) are renowned for their extraordinarily fast rates of growth.

How Fast Do Spruce Trees Grow?

Spruce refers to the Picea genus of plants, which includes 35 separate species.

Varieties Top Growth Rates The Sitka spruce dwarfs its cousins in maximum attainable height and rate of growth. During its 500-year life, a Sitka spruce will reach between 160 and 220 feet, with 60-inches-per-year growth rate until it reaches maturity. Coming in second with an average growth rate of 30 inches annually, the Norway spruce has an impressive yet manageable height between 40 and 60 feet.

With a branch spread of 25 feet across, landscape designers will often arrange Norway spruces to provide privacy and wind blockage for houses on larger lots.

While the growth rate for the Colorado blue spruce (13 inches per year) is slower than that of the Norway spruce, the former reaches a soaring 90 to 135 feet in height. Factors That Limit Growth Spruces need space. At maturity, these three species have massive branch widths, ranging from 20 to 30 feet across.

If spruces are planted too close together, root problems arise that lead to blight in the lower limbs. Likewise, immature spruces grow best in direct sunlight, so try to avoid planting them near taller, mature trees. Spruces also are vulnerable to drought. In hot, dry weather, the young trees need to be watered at least once a week. Conversely, spruces' root systems need good drainage to thrive; planting them in a sandy or clay soil helps prevent puddles from building up.

A number of parasites target spruce trees, namely the spruce budworm and spider mite. In addition to slowing or stopping vertical growth, these pests can cause lower limbs to die and ruin the tree's symmetry.

Fortunately, most arborists offer convenient and affordable spray treatment services to eliminate these pests on an annual basis.

In particular, spruce and pine trees show needle browning and dieback. Spruce trees have small needles arranged along the stem. Pine trees have needles in bundles of two, three, or five along the stem. Spruce trees are experiencing three different diseases, each with slightly different symptoms and treatment.

News Release

News Release Evergreen Dieback Problems This article was originally published on July 6, 2011 and expired on September 1, 2011.

It is provided here for archival purposes and may contain dated information. Many evergreen trees are experiencing needle dieback this year. According to Rhonda Ferree, extension educator in horticulture, the cold, wet spring has brought out many tree diseases that are causing significant damage on evergreens throughout central Illinois.

First is Rhizosphaera needle cast. Spruce trees with purple/brown one- and two-year-old needles are suspect. The newest growth will appear green. Affected needles are cast (dropped). Since evergreens do not re-foliate along the branches, the disease will cause bare areas scattered throughout the tree. Norway spruces are considered resistant to this needle cast while Colorado blue spruce is a common host.

The second disease we see regularly on spruce in Illinois is Cytospora canker. That disease causes entire branches to turn purple/brown. Cytospora affects all needles from the tip of the branch to the base. Often lower branches are affected first.

The disease may progress up the tree slowly, killing branches over a number of years. The fungus is known as a stress pathogen, meaning it invades spruce trees growing in less than ideal sites or environmental conditions. Third, the University of Illinois Plant Clinic recently confirmed a new spruce disease in Illinois called Sudden Needle Drop (SNEED).

SNEED has been found on Norway, white and Colorado blue spruce trees. Symptoms of SNEED are yellowing and eventual browning of older needles. Typically, by the end of summer, all of the needles on affected branches fall off except the newest needles on the tips of the branches. Pines are prone to several diseases as well, including diplodia blight, pine wilt, and Dothistroma blight. All three diseases will cause needles to turn brown. The pattern of symptoms will help with diagnosis in each case.

The main disease that Rhonda has seen this year is diplodia on Austrian Pine. Diplodia tip blight causes entire needles to turn brown, not just tips of needles as might occur with Dothistroma blight, scorch, salt injury, or transplant shock. Diplodia blight causes all of the needles at the tip of a branch to turn brown. Several practices can help reduce the amount of damage caused by these diseases.

When the foliage is dry, remove dead branches and dead stem tips. Because the fungus survives on cones, rake and remove fallen cones throughout the season.

Stressed trees are typically more susceptible to infection, so follow proper watering and fertilization to keep trees healthy. Chemical options are available for some diseases, but sprays this late in the season are not beneficial.

For more information on these diseases and more, read the Home, Yard, and Garden Newsletter from University of Illinois Extension at http://hyg.ipm.illinois.edu/index.php.

Blue Spruce: The species is native to the United States and is known for its long life span and appealing shape. The slow-growing Spruce is a popular Christmas tree thanks in large part to the fact that its needles do not shed easily.

The large evergreens are a holiday staple, featuring an attractive pyramid shape and stiff needles.

While the trees are a top pick to bring indoors during the month of December, there are ways to enjoy the specimen year-round in your own back yard. Appearance of the Tree Spruce Tree Needles Spruce trees belong to the genus Picea and can grow up to heights that exceed 100 feet tall. The trees have a number of key characteristics that help them stand out from their coniferous cousins: Leaves: Spruce trees feature stiff needles which range in color from silvery-green to blue-green depending on the type of specimen.

The needles often curve inward and measure about three quarters of an inch long. Bark: The grayish-brown bark sports a moderate thickness. It forms furrows, ridges and scales as the tree matures. Fruit: Light brown, slender cones with diamond shaped scales contain seeds which are transported by the wind.

The cones typically fall from the tree shortly after the seeds are dispersed. Another distinguishing characteristic of the Spruce tree is its longevity. Some types can live up to 800 years thanks to their ability to withstand extreme weather conditions.

Christmas Spruce Spruce Tree Bark Spruce Tree Cones Spruce Tree Types Blue Spruce Tree There are more than three-dozen different species of Spruce trees growing throughout the world. Among the most popular are:

Along with its excellent needle retention, the Blue Spruce is prized for its natural triangular shape. Red Spruce: Landscapers are particularly fond of the Red Spruce as it has the ability to prosper in a number of different environments, including rocky upland so

ils. The tree has longer needles and cones than most Spruces and its wood has a reddish hue. White Spruce: This type of Spruce is especially popular in the United States where it grows from Alaska to New England. While it shares the same shape leaves as its cousins, the wood of the White Spruce is lighter and softer.

Spruce Trees

Spruce trees are native to the western United States and Canada. The Colorado blue spruce, also called the silver spruce, was first discovered on Pikes Peak in 1862. Blue spruce can live 800 years. White spruce has a life expectancy of 200 or more years, with some 300-year-old specimens documented in Manitoba, Canada.

The evergreens especially are prized in landscapes for their year-round color. Conifers are generally hardy plants that can withstand extreme growing conditions; their more than 500 species are found in nearly every climate on Earth. Conifers are also considered the longest-lived woody plants on the planet, older than flowering plants by millions of years. Pines

Conifers are known for their longevity, with pines among the oldest trees on Earth. Ponderosa pines, common throughout the western United States, have a lifespan of 300 to 500 years, with an 800-year-old tree documented in Utah.

The oldest-known trees in the U. S. are bristlecone pines, another native of western states, which are documented at more than 2,000 years old. The oldest tree in the U. S. is a bristlecone pine in the White Mountains of California, appropriately nicknamed “Methuselah,” which is said to be more than 4,700 years old.

Redwoods California’s storied redwood trees are probably best-known as the tallest trees in the world, towering 350 to 400 feet tall. The conifers are a fast-growing tree, growing 3 to 5 feet per year in the first five years and reaching 90 feet tall by 25 years.

The average life span of a redwood tree is more than 600 years. Only two species of redwood trees are still found in North America, the coast redwood and the giant sequoia. Spruce

One of the easiest ways to tell the difference between a spruce tree and a pine tree is by looking closely at their needles. While spruce needles tend to be shorter than those of pines -- roughly 1-inch long -- it's their notable stiffness that really gives them away.

Each sharp needle erupts from the branch on a tiny, woody peg. Pine needles, on the other hand, are so soft and flexible that they produce the tell-tale whisper as wind moves through them.

Cones & Bark With papery-thin scales that give their cones an almost flexible feel, spruce cones hang down on the branch, pointing toward the ground.

Pine scales are noticeably thick, rigid and tough. Spruce bark typically feels rough when you run your hand across it, with a thin and scaly look that grows more furrowed as the tree ages. Pine bark in general is smooth when the tree is young but with age often develops a reddish-brown color and starts to flake.

Spruce Tree: Comments, Trivia, Reference Spruce Trivia: Spruce trees that grow near rivers where salmon spawning runs occur, grow two to three times taller.

The Fraser River in British Columbia, Canada is an example of this phenomenon. Why? Because, when bears catch a large salmon, they like to go into the woods to eat the best fatty parts.

Bears leave over half of the remaining salmon which decomposes on the spruce forest floor . Decayed salmon provides extra rich nitrogen fertilizer to the soil, producing better growing conditions which leads to taller spruce trees. The Sitka Spruce, picea sitchensis, is one of the largest spruce trees. The wood, which is easy to work with, has good acoustic properties and is therefore popular for making musical instruments.

Generally, they do, but look closer. Feel the needles. Spruces have stiff, prickly needles, while Douglas-firs and true firs have soft, flexible needles. Each spruce needle springs from a tiny, woody peg; in fact, this peg is one of the best ways to identify a spruce.

Spruces ( Picea)

"Spruces ( Picea)Spruce needles are generally stiff and sharp; about 1"" long. Each spruce needle springs from a tiny, woody peg. Most spruce cones have papery thin scales. Most spruce bark is thin and flaky. Many people think that spruces, Douglas-firs, and the true firs look alike.

Spruce cones hang down from the branches like those of Douglas-fir while true fir cones stand up, but spruce cones do not have Douglas-fir's pitchfork bracts. The scales of most spruce cones are papery thin--yet another difference. And spruce bark is scaly--Douglas-fir and the true firs have smooth or ridged bark.

There are approximately 40 different species of spruce in the world, but only 3 are native to the Pacific Northwest--and only 2 of those are common.

Location is probably the best clue to their identity. Sitka spruce: grows only along the Pacific coast, from northern California through southeastern Alaska, and only near sea level. Needles are often (but not always) flat in cross section and are typically very sharp. Needles point in two distinct directions: perpendicular to the twig and toward the tip.

Most needles are 2 distinct colors: green above and blue-green to white below. Engelmann spruce: grows only in the Cascades and Rocky Mountains, from central British Columbia through New Mexico, and only at high elevations. Needles are typically square in cross section, and range from being very sharp to blunt. Most needles point toward the tip of the branch.

Most needles are a single color, either all green or all blue-green. Brewer spruce: Quite rare; grows only in the Siskiyou Mountains of southwestern Oregon and northern California. Needles are typically square in cross section and are blunt on their ends. Needles point toward the tip of the branch and each needle is a single color.

Blue Spruce Trees- Which Variety is Bes

Blue Spruce Facts Blue spruces are in the spruce family, Picea. The spruce tree was used in ancient times for caulking ships, as the name picea is derived from the Latin word for “pitch”. They are known for their long life, and their short, rigid, sharp pointed needles that range in many colors.

Spruces are the most popular of all the conifers, and they many types different types of spruces. The bluest of the spruce family, is the tall, symmetrical, and formal-looking Colorado blue, P. Pungens ‘Glauca’. It is a native of the Rocky Mountains, but is hardy in Zones 3-8, but is not at its best in warmer regions.

The soft silvery blue-gray foliage turns silver-gray to blue-green as the tree matures. It grows slowly to 30 to 50 feet and can live 600 to 800 years. The cultivar ‘Foxtail’ has a greater heat tolerance than other varieties. Blue spruce trees are very popular as Christmas trees. Blue Spruce ‘Glauca Globosa'Blue spruce trees are also used as windbreaks, as well as single specimens.

An example of needle rust is beginning to show up on spruce trees near water. Spruce needle rust overwinters on Labrador tea and leather leaf and spores from these alternate hosts have moved to the spruce trees via wind and rain events and are now infecting spruce trees.

Spruce needle rust disease

Spruce needle rust disease Posted on July 24, 2009 by Dennis Fulbright, Michigan State University Extension, Department of Plant Pathology Tweet Pin It Editor’s note: This article is from the archives of the MSU Crop Advisory Team Alerts.

Check the label of any pesticide referenced to ensure your use is included. Rust fungi represent some of the most advanced fungal species known. Because rusts are complex diseases they can be described in many different ways. You can categorize them by their life cycles, their spore colors, their primary or alternate hosts, or the types of symptoms they cause.

Using both symptoms and the conifer host is probably your best bet in identifying the rust diseases of Christmas trees in Michigan. Basically, there are two types of rusts on Michigan Christmas trees; those that cause diseases of stems and twigs and those that cause diseases of needles.

In July and August, yellow current-year needles with whitish blisters filled with yellow spores will appear on Colorado blue, black and white spruce. Shedding of infected needles will follow these infection episodes. The alternate hosts, Labrador tea leather leaf are members of the Heath family and are found in bogs and damp thickets.

Care should be taken to plant spruce away from wetlands especially the rust susceptible Colorado blue, black and white spruce. Norway spruce is more resistant. Scouting for alternate hosts, roguing infected branches and trees and planting resistant stock can reduce the impact of many of these rust diseases. Spruce needle rust.

. The Norway Spruce, a European native, was probably the original Christmas tree. The Blue Spruce is the state tree of Colorado and Utah, plus the U. S. National Christmas Tree is also a Blue Spruce. Description Spruce trees are large, with some species maturing up to 200 feet tall. They have a strongly conical shape, especially when they are young.

Spruce Tree

Spruce Tree By Lou Paun Master Gardener Source Source Whether you can fit one in your garden or you simply love to walk amongst them in the forest, the majestic spruce tree offers a level of stature to any landscape.

Picea Common Name: Spruce Picea pungens Common Name: Blue Spruce, Colorado Spruce Picea abies Common Name: Norway Spruce About the Spruce Tree Spruce trees are coniferous (needle-leafed) evergreens. There are about 35 species in the genus Picea, native to the northern hemisphere. The name spruce is from the Latin pix, meaning pitch.

These trees often live to a very old age. The oldest spruce on record is a Picea engelmannii that reached 852 years and is still thriving

The branches are quite rough, showing small bumps where old needles have shed. Blue Spruce Source Blue spruce trees have thin, rather scaly bark and pendulous cones.

The needles are at nearly right angles to the branch and have extremely sharp tips. Blue spruces mature to a 50- to 75-foot height with a spread of about 25 feet. This tree is admired for its beautiful silver-blue color. Norway Spruce The Norway spruce tree is a deep, bright green. The needles are quite square when a cross-section is examined. They have the longest cones of any spruce, up to 6.5 inches.

Some weeping forms have been developed for landscape use. Scientific Classification Kingdom - Plantae Division - Pinophyta Class - Pinopsida Order - Pinales Family - Pinaceae Genus - Picea Cultivation Norway Spruce Picea abies grows well in full sun and cool temperatures.

It is best in acidic, sandy soils and it prefers good drainage. This spruce tree grows quickly and transplants easily. Blue Spruce Picea pungens grows best in full sun. It is tolerant of a wide range of soils and prefers average moisture.

It has some tolerance for both flooding and drought. Blue spruces are hardy in zones 2 to 8 and grow at a slow to medium rate. Uses Spruce trees are grown as screens, windbreaks, and specimen plants. They are admired for their year-round color, symmetrical growth pattern, and conical shape.

Blue Spruces and Norway Spruces are popular Christmas trees and both have dwarf forms that can be grown in small gardens. Norway spruces are widely planted to replace forests. Spruce forests are often cultivated for paper manufacture.

The long fibers of spruce wood are especially suitable for this purpose. Spruce wood, which is sometimes called whitewood, is used for a variety of purposes ranging from general construction work and crating to the bodies of stringed musical instruments and wooden aircraft.

Traditional uses include using the resin to make glue and pitch; the saplings for snowshoe frames and bows; the bark for cooking pots and trays; the roots of some species for baskets; and decayed wood for tanning. The needles and branches have been used to brew beer. Problems The spruce beetle is the most dangerous pest for Picea.

The spruce gall aphid and the spider mite can also be troublesome. In general, however, spruce trees have little trouble with pests and diseases.

The spruce trees of North America include seven different species, all of them growing north of Mexico, mostly in cool climate locations. Spruce trees are important producers of lumber and are also useful in an ornamental capacity. The spruces all have evergreen needles, most are tall and they have a conical shape.

Types of Spruce Trees

"Home »Trees Types of Spruce Trees By John Lindell; Updated September 21, 2017

White Spruce White spruce’s range is “transcontinental,” according to the Nearctica website, as the tree grows from Labrador to Alaska, covering most of Canada and many of the northernmost states. White spruce grows to 150 feet tall and features blue-green needles. The odor that crushed needles produce gives the tree the nickname of skunk spruce.

White spruce can withstand the shade and its penchant for growing best in damp, loamy areas means it is common along lakes and rivers throughout its range. White spruce suffers from insect pests such as the spruce budworm, which can severely damage the tree if infestations occur in consecutive years.

Black Spruce Black spruce shares a similar range with white spruce; among coniferous species in North America, the “National Audubon Society Field Guide to Trees” says that only common juniper has a wider distribution than these two spruces. Black spruce rarely will be as tall as 100 feet, with most in the 20- to 40-foot range. Black spruce has grayish-black bark and prefers moist sites, growing in bogs and around swamps. In areas with heavy snowfall, the lower branches of black spruce will actually take root after the snow bends them to the ground.

This can result in a ring of smaller trees around a larger specimen. Sitka Spruce No spruce in the world can grow taller than the Sitka spruce, a species that exceeds 200 feet on occasion, with a diameter of 5 feet.

The Sitka spruce grows along the coastal areas of the Pacific Northwest. The tree excels in damp, foggy air and resists any problems that salt spray can cause other trees. Weevils and aphids are pests that damage this tree. Sitka spruce can start to decay when it suffers an injury to its trunk.

Despite its large size, the Sitka spruce produces cones that are usually only about 3 1/2 inches long. Red Spruce The red spruce is a medium-sized tree, attaining an average height of 50 to 80 feet. Known as an attractive ornamental spruce, the red spruce occurs in the Northeast and into the Appalachians. The red spruce requires a cool and damp climate to thrive and this species does well in acidic soil.

Red spruce shares the trait of developing shallow roots like most spruces do, meaning it is wise to plant it where it gets some buffer from the wind. While certain fungi may infect weakened and old red spruces, this spruce is quite resistant to most diseases, notes the National Forest Service website.
