This small tree, commonly grown for its stunning reddish-brown bark, offers exceptional features throughout the year. Stewartia monadelpha, otherwise known as tall stewartia or orangebark stewartia, is just getting ready to come into bloom this month. Its white camellia-like flowers burst forth in early summer, followed by interesting brown seed pods and rich russet fall color.
