Plant Profile: Cotinus obovatus

The American smoke tree, indigenous to the southern United States, is a small tree or upright shrub that falls under the Anacardiaceae family and requires moderate maintenance. It thrives in well-drained, nutrient-poor loam soil and prefers full sunlight, although it can adapt to a variety of soil types, including clay and shallow rocky conditions.

The term "smoke tree" is derived not from its inconspicuous green-yellow flower clusters, which are dioecious and bloom during the summer, but rather from the delicate, smoky pink to pink-purple hairs that adorn the spent flower clusters, creating a soft, misty appearance. This summer display of "smoke" makes it a visually appealing accent plant. Additionally, it boasts some of the most vibrant fall colors among native American trees and shrubs, making it an excellent choice for mass planting or as a backdrop in shrub borders. However, it does require a considerable amount of water, particularly in dry spells, and is notably resistant to deer damage.
