This shrub’s most striking feature is its reddish brown, exfoliating bark which can be seen from a distance. Flowers do not have the “wow factor” of C. alnifolia and have only a trace of the spicy perfume of C. alnifolia. Becomes almost a small tree with age and looks best with an underplanting of woodland ferns and wildflowers. Although will grow in full sun, does best in part shade. Attracts bees.
