- Description
-
Calycanthus floridus, commonly called Carolina allspice, is a dense, rounded deciduous shrub with a suckering habit which grows 5-6' tall with an equal or slightly greater spread. Sweet shrub grows best in average, medium, well-drained soil in full sun to part shade. It will grow somewhat taller in shade than in sun. It is tolerant of a wide range of soils, but prefers rich loams. Prune immediately after flowering to shape or maintain compactness. It tends to sucker and often forms colonies in the wild. Remove root suckers promptly if naturalization is not desired.
It is best to purchase this plant when in flower because the quality and intensity of the fragrance can vary widely from plant to plant. Also commonly called sweetshrub and strawberry bush in reference to the fragrant blooms which have been described as combining hints of pineapple, strawberry and banana. Further common name of hairy allspice is in reference to the hairy twigs and leaf undersides of this plant.
TOXIC ONLY IF LARGE QUANTITIES EATEN.
