There are about 35 species of evergreen coniferous trees that fall under the spruce flag. They grow in the temperate and boreal regions of the Earth's north. These species tend to be resilient trees that add color all year round, starting with deep green and blue-green needles. We have uprooted three of the common spruce trees.
In botany, an evergreen is a plant that has foliage that remains green and functional for more than one growing season. This also applies to plants that retain their foliage only in warm climates, and contrasts with deciduous plants, which completely lose their foliage during the winter or dry season. The binomial Latin term sempervirens, which means evergreen, refers to the perennial nature of the plant; for example, the longevity of leaves in evergreen plants ranges from a few months to several decades (more than thirty years in the bristly pine of the Great Basin). Perennial and deciduous species vary in a variety of morphological and physiological characters.
In general, broadleaf evergreen species have thicker leaves than deciduous ones, with a greater volume of parenchyma and air spaces per unit of leaf area. They have a higher leaf biomass per unit of leaf area and, therefore, a lower specific leaf area. Construction costs do not differ between groups. Evergreens generally have a larger fraction of the total plant biomass present in the form of leaves (LMF), but they often have a lower rate of photosynthesis.
In areas where there is a reason to be deciduous, for example,. In a cold or dry season, perennial plants are often an adaptation of low nutrient levels. In addition, they tend to have hard leaves and have an excellent water economy due to the scarcity of resources in the area where they live. The excellent water economy in evergreen species is due to their high abundance compared to deciduous species.
Whereas deciduous trees lose nutrients every time they lose their leaves. In warmer areas, species such as some pines and cypresses grow on poor soils and disturbed land. In rhododendron, a genus with many broadleaf evergreen trees, several species grow in mature forests, but are generally found in highly acidic soils where nutrients are less available to plants. In the taiga or boreal forests, it is too cold for organic matter in the soil to decay quickly, so soil nutrients are less available to plants, which favors evergreens.
It is possible to identify different evergreen trees such as pines, firs and firs by looking closely at their needles and cones. White pines hold their needles in groups of five. The needles of spruce and fir trees are usually connected in a unique way. For example, although it is evergreen, the foliage of red cedar changes color a little during the winter.
For most of the year, the foliage is green with a blue tint. In winter it may show more shades of brown. Fir trees are very popular in the United States and the rest of the world because they make great Christmas trees. Their name refers to their ability to grow tall and often reach more than 200 feet when fully developed.
You can find these trees throughout North and Central America, as well as in Europe, Asia, and North Africa. Fir trees have cones that stand upright, like camels, and their needles appear to be attached to the branch by suction cups. Pines look a lot like spruce trees. In fact, people have often called them skins throughout history.
Like spruce, pine grows very tall and can often exceed 250 feet when fully developed. These trees often lived for several hundred years, they almost have thick, scaly bark. Pine needles are grouped in groups of 1 to 7 and can persist on the tree for 40 years. Junipers are a diverse species that can exist as a shrub or as a tree.
The female juniper has fruit-like seeds that almost look like blueberries, and many varieties have two types of leaves that change as the plant ages. You can find junipers in a wide variety of environments, including rock gravel and planted soil. People often think of hollies during the Christmas holidays because of their attractive appearance that adapts to the season. However, these trees are widespread in many temperate and subtropical regions of the world.
These trees are small and slow-growing, generally not growing more than 80 feet tall. Tuya trees are a small group of tall, slender trees that typically grow 10 to 200 feet tall. Thuya is a popular tree for property division and is also ornamental. Two species are native to the United States and you can find them as far north as Alaska.
They have a reddish-brown bark and a lightweight wood that is easy to split but that resists decay. You can call a cryptomeria tree Japanese cedar or Japanese sequoia if you have difficulty with the official name. These trees can grow up to 230 feet tall and have bark that comes off the tree in long vertical stripes, giving them their distinctive appearance. China claims to have trees of this species that are more than 1,000 years old.
Olive trees are an important cash crop for many countries, especially Italy, Australia and New Zealand. Please, trees grow to almost 50 feet tall with silvery green leaves on a twisted and twisted trunk. It produces small white flowers before the fruit that gives it its name. Fossil evidence says that these trees grew for millions of years, and humans may have already been eating them 6,000 years ago.
Hemlock trees are native to the northeastern United States and generally grow very little, over 100 feet tall. They have a very long lifespan and a tree in Pennsylvania is estimated to be over 500 years old. It is popular for railroad flanges because it holds the barbs firmly. These trees prefer higher altitudes with plenty of rain.
The spruce is a large family of trees found in temperate zones north of the equator. It is another evergreen tree with a long lifespan, and a tree in Norway is estimated to be over 9,500 years old, making it the oldest tree in the world. These trees are extremely versatile and we use them for tonewood and musical instruments. It's also an important ingredient in paper, wood, and medicines.
The cypress is a large group of trees and shrubs that you can find all over the world in the temperate zone. These trees can grow over 200 feet tall, and you'll often see them decorating a park or church because of their ornamental appearance. Wood may be valuable, but it's not as popular as other species such as oak or pine. The arborvitae tree is a wide variety of property dividers due to its tall, slender growth style.
A fully grown tree can often reach 75 feet tall and typically grows at a rate of three to four feet per year. These trees are attractive and don't require much care. You only need to provide them with about an inch of water per week to keep the tree healthy. Yews are slow-growing, long-lived trees that generally reach about 65 feet in height.
All parts of the plants are toxic to humans, so it's not a good option if you have young children who like to play in trees. You'll see these trees frequently in church cemeteries, and many people consider them a sign of sadness. The wood has a yellowish brown color, and carpenters use them to make long arches because of the elastic nature of the wood. Eucalyptus is a large family of plants native to Australia, and you can find them everywhere on the continent.
It is a fast-growing wood that can be used for paper, honey, wood or essential oils. Many carpenters also use it for wood, but it's highly flammable, so you can't use it for homes. Some varieties can grow up to 200 feet or more, while others stay much closer to the ground. As you can see, there are several varieties of evergreens that you can use for ornamental purposes or as a solution to a problem such as lack of privacy or excessive wind that creates accumulations of snow on your property.
Pines and firs are extremely easy to find and grow almost everywhere in the United States, so they're a great choice for beginners or someone who wants to create a barrier between properties or avoid wind. Cedar is also a great choice because it repels insects, including fleas and ticks. If your need for an evergreen tree is strictly decorative, hopefully the images above will give you what you need to select your favorite. .
