Hymenosporum flavum - Sweetshade
Sweetshade is an evergreen with a narrow upright growth habit, with leaves that form clusters at the ends of branches. In spring, fragrant flowers bloom in pale cream, deepening in color to bright yellow. It can be pruned early to strengthen branches. Reaches heights of 20-35 feet and grows about half as wide. Light pruning after flowering will help maintain your desired size and shape if needed.
