Facts About Aspen Trees

Perhaps the most fascinating tidbit about aspen trees is how it exists in the collective. Aspens have a 'root system' that exists underground, basically operating as its main life force. This root system is connected to multiple individual trees, all of which together make what is known as a 'stand'.

• Each plant in an aspen stand is considered a generic replica of each other.
• The name given to each stand is a clone. The oldest aspen clone, called Pando, is in Utah, dating back over 80,000 years.
• Younger aspen groves, from around 10 years old, provide the perfect habitat for ruffed grouse with their dense foliage and flower buds, doubling up as food for the birds.
• Aspen clones can take up as much as 43,560 sq ft (404,686 sq m) of land!
• The name quaking aspen comes from the whisper-like rustling that can be heard in aspen groves in the presence of a light breeze.
• There is some debate around the toxicity of aspen trees, but it's proven to be harmless when consumed in small quantities like in tea. It's not recommended to ingest large dosages, as the human digestive system cannot handle too much.
• The Greek word for aspen is 'aspis' which means shield. It was believed to have magical protective features.
• In many beliefs, the aspen tree is considered to be a protector and inspires adventure and bravery in people. The leaves were used in the crowns of Greek heroes.

Different Uses Of Aspen Trees

As with many other woodland trees, aspen trees are also wonderful natural resources with different uses.

• Their bark and leaves can be used in a medicinal capacity, particularly when combined with other herbs.
• This concoction is often used for body aches, joint pain, nerve trouble, and bladder troubles.
• It's also a widely used wood in the timber industry.
• Aspen tree ecosystems are extremely rich and diverse places for the growth of flora and fauna.
• Aspen underbrush is especially helpful for cattle and sheep, grazing in North America.
• Since it's less flammable than other types of wood, it's often used in making paper and matches.
• Shredded aspen bark is used for animal bedding since it’s considered much less inflammatory than other alternatives.
• Many places also heat-treat aspen to use it as a lining for the interior of saunas.
• The aspen trees' leaves, bark, and twigs are a principal food source for beavers. Their branches are further used to build little dams by these beavers.
• They are also considered as nests by hair woodpeckers and yellow-bellied sapsuckers, which create a hollow in their trunks for this purpose.

Characteristics Of An Aspen Tree

Aspens are found in a lot of places, like parks and woods, including your backyard. To get rid of those pesky little shoots, you have to inject a dose of herbicide directly into their trunk. This way, their root system gets nullified and you can pull out the whole plant without worrying about regeneration or seeds spreading everywhere.

• Aspen is a deciduous tree. Aspen leaves are shed once a year during fall.
• Their lifespan is up to 150 years, although a few have been known to survive for over 200 years.
• Aspens grow from anywhere between 20-80 ft (6-24 m) in height, making them firmly medium-sized with lengthy stalks. They can be 3-18 in (8-41 cm) in diameter.
• Aspen tree leaves are 1-3 in (25-76 mm) in diameter. They’re almost round with a thin, firm texture.
• The flat leaves have long stems that are pressed along one side, with a pattern that looks like teeth going along the rounded shape.
• Their bark is white-gray, smooth to the touch, getting rougher and textured with age.
• The flowers of an aspen tree are small, white in color, and bloom during spring.
• Aspen trees have the ability to regenerate through vegetative spores.
• This type of tree is extremely sensitive to fires. While they don’t burn readily, they become more stimulated after a fire, leading to an increase in numbers.
• These are some of the fastest-growing trees out there, growing up to 60 in (152 cm) per year under favorable conditions!

Ideal Growing Conditions For Aspen Trees

Aspens are aggressively growing trees due to the diversity of environments and climates they can survive in and the pace at which it spreads. Aspen grows very quickly through seeds and roots sprouting, often without deliberate intention.

• Due to how fast these trees grow, they are a good option for those wanting to harvest their own wood for furniture.
• Aspen trees are best grown in moist and sunlight-rich areas, with minimal shade and obstruction.
• In the wild, quaking aspen has been seen in various conditions, from Rocky Mountain states to colder regions like Canada and Alaska.
• An aspen plant can be grown in a pot in a greenhouse or a backyard without much difficulty, provided you do some research beforehand.
• Nursery-grown specimens of aspen trees are popular options for landscaping, but they only have a lifespan of about 25 years.
• This kind of plant has been extracted from its roots system and needs different conditions to survive. Like a relatively cooler climate and well-drained soil.
• The soil for growing aspen trees must be fairly acidic for best results.
