Outstanding Qualities Orangebark stewartia is an outstanding tree for year-round interest. Its delicate, white, saucer-shaped flowers dot the braches in June and early July. The dark green foliage becomes a brilliant mix of rich red-orange and fire engine red in the fall. As the leaves drop, they reveal the beautiful cinnamon brown bark of the trunk and branches. No serious insect or disease problems are common to this tree. This tree will work well in small yards. The bark is shown to perfection with a backdrop of evergreens.
Culture This stewartia grows best in partial shade. It will tolerate full sun if kept out of hot spots (for example, against a reflective wall) and watered attentively. It thrives in humus-rich, well-drained soil.
Growing Habit Usually grown as a single-trunk tree with a graceful layered branching habit, Stewartia monadelpha is slow growing, reaching about 15 feet high and 8 feet wide in ten years. It matures to 25 to 30 feet high and 15 feet wide and makes an elegant specimen tree.
Hardiness USDA zones 6 to 8
