Every once in a while, a plant will stand out and demand to be appreciated. Recently, I received a request from a guest in the park about the identification of a really interesting plant adorned with purple foliage—the smoke tree, Continus coggygria. We receive many questions about this plant each year, and for good reason. The deep reddish purple foliage is eye-catching, but even more so are the airy panicles of flowers that the plant gets its name from. The flowers appear like soft plumes of smoke floating around the plant in late spring.
This species is native to temperate Asia and Europe and was introduced to the United States in the 1950s. Interestingly, this plant belongs to the plant family of Anacardiacea, which includes species like sumacs, economically important cashews, and much reviled poison ivy.
When visiting, you may notice a variety of pruning techniques as we often cut back some of the purple smoke trees in the springtime.

Another fun fact about this beautiful plant is that it has a North American cousin, our native smoke tree, Continus obovatus. This species is native to rocky areas from Kentucky, Tennessee, Alabama, and Oklahoma. It produces the same beautiful panicles of flowers but features a bluish green leaf and yellowheart wood. We have both the purple smoke tree and the native smoke tree on display at Gathering Place, and Sky Garden is where you can view them.

Bright moments, and see you in the park!
