Tall Stewartia (Stewartia monadelpha)
The Tall Stewartia is a small to medium tree with all of the attractions of the other species. Michael Dirr, in his Manual of Woody Landscape Plants, writes that the Tall Stewartia is heat tolerant and is one of the best Stewartias for southern gardens.
The flowers of the Tall Stewartia are a bit smaller at 1 ½ inch cup shaped white with violet anthers in the middle. Flowering lasts for about 4 weeks starting in mid-June in Zone 7
