The Drake elm (Ulmus parvifolia ‘Drake’) is a variety of the Chinese elm (Ulmus parvifolia) tree. While both trees belong to the same species, there are some distinct differences between them.
1. Growth Habit:
The Drake elm has a slightly more weeping habit compared to other Chinese elms. This means that its branches tend to cascade downward, creating an elegant and graceful appearance. On the other hand, Chinese elms typically have a more upright and spreading growth habit.
2. Bark Exfoliation:
One notable difference between the two varieties is the timing of bark exfoliation. The Drake elm begins exfoliating its bark at a younger age and at a smaller size compared to other Chinese elms. This means that the older bark peels away, revealing the lighter, smoother bark underneath. This unique feature adds visual interest and texture to the tree’s overall appearance.
3. Leaf Color in Fall:
During the autumn season, the leaves of the Drake elm turn a flat yellow color. This is true for most Chinese elms as well. However, it is important to note that leaf color can vary slightly depending on factors such as climate, soil conditions, and individual tree health. Nonetheless, the flat yellow hue of the leaves adds a touch of warmth to the landscape during the fall months.
4. Tolerance to Environmental Conditions:
Both the Drake elm and other Chinese elm varieties are known for their ability to thrive in a wide range of environmental conditions. They are highly adaptable and can tolerate different soil types, including clay and sand. These trees are also relatively resistant to pests and diseases, making them a popular choice for urban landscapes and gardens.
5. Overall Appearance:
In terms of overall appearance, the Drake elm and other Chinese elms share many similarities. They both have small to medium-sized leaves with serrated edges. The leaves are dark green in color and provide a dense canopy of shade. The trunks of both trees have a distinctive mottled appearance, with patches of gray, brown, and green bark.
While the Drake elm is a variety of the Chinese elm, it has some distinct characteristics that set it apart. Its slightly weeping growth habit, earlier bark exfoliation, and flat yellow leaf color in fall make it a unique and visually appealing choice for landscaping. However, both the Drake elm and other Chinese elm varieties exhibit similar overall characteristics, including adaptability and resilience to various environmental conditions.
