About

Calycanthus floridus, commonly referred to as spicebush, is a robust, multi-stemmed deciduous shrub that often develops suckers. It features oblong to oval leaves that are dark green on top and have a hairy texture on the underside, turning yellow in the fall. In May, the shrub produces highly fragrant flowers with dark brownish-red, strappy petals, which emerge at the tips of short branchlets. The scent is a unique blend reminiscent of pineapple, strawberry, and banana. After flowering, urn-shaped fruit capsules develop and remain on the plant during the winter months.

Care notes

Cultivation
Prefers moderately fertile, humus-rich, moist but well-drained soil in partial shade where it grows taller, but tolerates a wide range of soil conditions and some sun. Shelter from cold, drying winds. Autumn colour is better in its native habitat.
Pruning
Prune immediately after flowering to shape and maintain size. Remove root suckers promptly. Tends to form colonies in the wild.
Propagation
Propagate by softwood cuttings
Pest resistance
Generally pest-free
Disease resistance
May be susceptible to honey fungus (rarely)
