The difference between American Aspen and European Aspen lies in several characteristics, including the appearance of their leaves, their color changes throughout the seasons, and their method of propagation.
1. Leaf Characteristics:
The leaves of the European Aspen are more coarsely toothed compared to the American Aspen. This means that the edges of the European Aspen’s leaves have larger and more noticeable teeth, giving them a slightly different appearance than the American Aspen’s leaves. This distinction can be useful when identifying the two species.
2. Color Changes:
Both the American and European Aspen species exhibit distinct color changes throughout the year. In the case of young leaves, they initially have a copper tint before transitioning to a vibrant green color as they mature. This copper tint can be particularly striking and adds a unique touch to the overall appearance of the Aspen tree during its early growth stages.
As autumn approaches, both American and European Aspen trees undergo a stunning transformation. The leaves turn a vibrant yellow before eventually falling to the ground. This vibrant yellow coloration is a characteristic feature of both species and adds a beautiful touch to the landscape during the fall season. It is worth noting that this color change is more pronounced in Aspen trees compared to many other deciduous trees, making them a popular choice for those seeking vibrant autumn foliage in their gardens.
3. Method of Propagation:
Another area where the American and European Aspen species differ is in their method of propagation. Both species can spread by producing suckers, which are shoots that originate from the tree’s roots and grow into new trees. However, the key distinction lies in where these suckers form.
In the case of American Aspen, suckers often form closer to the parent tree, within its immediate vicinity. This can result in clumps or groves of Aspen trees growing together, creating a beautiful and distinct visual impact. On the other hand, European Aspen suckers tend to form underground, away from the parent tree. This can lead to the formation of dense colonies of Aspen trees over a wider area, creating a different effect in the landscape.
The key differences between American Aspen and European Aspen lie in the appearance of their leaves, the color changes they undergo throughout the seasons, and their method of propagation. By understanding and appreciating these distinctions, gardeners and landscapers can make informed decisions when choosing between the two species for their outdoor spaces.
