A unique native shrub famous for its fragrant, maroon-colored flowers and spice-scented bark.
Sweet Betsy, Sweetshrub, Carolina allspice, this plant has many common names and is an erect to rounded deciduous native shrub. It is found in the southeast growing in shady woodlands and along stream banks. It grows 6-12' tall with an equal or slightly greater spread. It is commonly called sweetshrub and strawberry bush in reference to the showy fragrant blooms which have been described as combining hints of pineapple, strawberry, and banana.
Sweetshrub grows best in average to rich, well-drained soil in anywhere from full sun to deep shade.
Prune immediately after flowering to shape or maintain compactness. It has a suckering habit meaning those suckering branches need to be maintained unless you want this plant to naturalize in your landscape. .
It withstands cold and heat, insect and disease pests, fire, and deer browsing. Plant it as a specimen or near a patio or walkway to enjoy its fragrance.
Calycanthus floridus seeds exhibit physiological dormancy, requiring a cold-moist stratification period to prepare for germination.
Sow seeds directly outdoors in late fall (October to early December) 1/4 to 1/2 inch deep in a prepared garden bed. The winter cold and moisture will naturally stratify the seeds, leading to spring or early summer germination. You can also prepare as for winter sowing.
Artificial Cold-Moist Stratification
90 days before you plan to sow in the spring, soak seeds in warm water for 24 hours to ensure hydration. Discard any floating seeds. Mix the viable seeds with a small amount of moist (not soggy) sand, peat moss, or vermiculite. Place the mixture in a labeled, sealed plastic bag and store in your refrigerator. Sow as described above.
The scientific name derives from the Greek words kaylx which means calyx, and anthos, which means flowers.
