Carolina Allspice (Calycanthus floridus): Fragrant Native Shrub for Shade

Overview

Carolina allspice (Calycanthus floridus), also known as sweet shrub, strawberry shrub, bubby bush, or sweet Betsy, is a deciduous shrub native to the southeastern U.S. Its unusual, maroon-red flowers emit a powerful, fruity fragrance reminiscent of strawberries, pineapple, and spice—hence the common names.

Botanical Description

Rounded, suckering shrub 1.8–3 m tall and wide. Leaves are opposite, ovate, 5–12 cm long, dark green, turning golden yellow in fall. Flowers are 3–5 cm wide, with numerous strap-like, reddish-brown tepals, blooming April–July. The fragrance is strongest in warm, humid weather. Fruit is a woody, urn-shaped capsule containing many seeds.
