Japanese Stewartia
by Mike Klahr, Ph.D.       #Hot Plants   #Trees

Are you looking for a pest-free, small-  to medium-sized landscape tree with multi-season beauty? Would you like to have a variety that does not show up on every list of The 25 Most Common Trees? Does the idea of showy summer flowers on a tree appeal to you? If so, you may want to consider planting a Japanese stewartia (Stewartia pseudocamellia). This tree is a beauty in all seasons — it offers good spring foliage followed by large, white, camellia-like flowers in June and July, and outstanding red, purple or yellow fall foliage color and incredible mottled bark with puzzle-like patterns of tan, olive green, ivory, orange, beige and gray.

Japanese stewartia should be planted in a prominent place in the landscape where it can serve as a year-round specimen plant. Choose a location with full sun or part shade in the afternoon, and then modify the planting site to provide a moist, acid, organic soil for best performance.
