Birch trees are definitely the one type of tree that makes me quiver. That is because it just happens to be the major tree that causes the large majority of my allergies. Unfortunately for me, I really love the appearance of the birch tree and obviously so do the developers in Alaska, because they seem to be everywhere, in many different varieties. While there are several different varieties of birch tree, here are the main ones to remember:
CRIMSON FROST BIRCH
This is one of the more attractive birch trees, and one that is mostly used in landscaping because of it's great white bark coloration and the beauty of it's red leaves.
This particular tree is capable of growing to about 30-35 feet tall, and have a spread of around 20 feet, making it perfect for most backyard tree covering. This type of tree does well in a variety of different settings including growing in clay, however, it still requires a medium to high level of sunlight.
YOUNG'S WEEPING BIRCH
This is one of my favorite types of birth tree. It has a strange look to it that definitely can add to a garden or a house. While many trees are generally symmetrical, this particular tree has virtually no symmetry to it at all. The tree generally has a noticeable stagger to one side, and has an interesting look, that really can add to any landscaping project if done correctly.
The tree itself grows to about 20 feet tall, and can spread out to about 15 feet. While it doesn't have the biggest stance, the weeping branches provide a great amount of shade and shelter for birds. This tree requires a great deal of moisture in the soil, with good circulation. It doesn't require all that much sunlight, but is fine when in a great deal of sunlight as well. Fairly versatile tree.
The nice thing about the yellow birch is the coloration of it's leaves, which are a beautiful yellow. This can add a great deal of appear to any yard or landscaping project. But one of the most significant thing about these trees is that they are capable of living from 150-300 years in the right conditions. This of course is an incredible amount of time, even for a tree. But my favorite aspect of the tree is that it has a natural wintergreen smell to it, especially when you clip the branches or the branches break. This can be smelled from quite some distance away, especially if you have several of them. This is most noticeable if you have several woodpeckers living in the trees as it provides a constant wintergreen smell from their constant pecking at the tree.
The tree itself grows to be about 60-80 tall, which is mostly attributed to their long life. They have a spread of about 30 feet, which makes them great for shade after they have been planted for many years. The tree requires moist soil on a regular basis, and are highly damaged by dryness. They are capable of thriving in most sunlight environments, however are normally used to a great deal of shade.
One of the more popular American trees, seen mostly in the northern regions, the Paper birch is an extremely beautiful birch tree with excellent noticeably white bark that flakes off relatively easily. This is why many Native Americans were able to use the bark in the manufacture of their canoes. This of course is a tradition that is still carried on today in many tribes across the country.
The leaves of the tree are yellow in the fall and green in the summer and have beautiful ridges, that really give them a beautiful appearance on the tree itself.
The tree grows to be able 50-70 feet tall, with a spread of around 30 feet. While the tree grows rather large, it isn't the best shade tree because of the low density of leaves on the branches.
This type of tree does really poorly in warm climates, as such you should really keep it in the northern areas of the country where it is native. This happens to be the most popular tree used for landscaping in Alaska, because of it's ability to withstand the colder climates. The tree does well in a variety of soil types as long as it is moist.
There are several other types of birch tree available, but those are the most common that are used in landscaping. Your best bet if you want a birch tree is to see what is available in your local area and what will grow well in your region. By doing this you are ensuring that you'll get the best possible birch tree for your particular region. Just keep in mind that if you leave in a warm climate, it will be difficult to keep one alive or healthy in appearance.
