A Brief History of Calycanthus Floridus
Carolina Allspice has deep roots in the southeastern United States, thriving in North Carolina, Georgia, and surrounding areas. Indigenous peoples and early settlers were among the first to appreciate this plant, not only for its fragrance but also for its medicinal and functional uses.
The plant’s common name, Carolina Allspice, reflects its spicy aroma, reminiscent of cinnamon, cloves, and allspice. Early Americans even used its dried seed pods and bark as a substitute for traditional spices in cooking—though it’s more ornamental than culinary today. Botanically, the shrub belongs to the Calycanthaceae family and was introduced to Europe in the 18th century, where it became a garden favorite.

Propagation and Planting Tips
Growing Carolina Allspice is a rewarding process, whether you start with seeds or cuttings. Let’s break it down:
Propagating from Seeds
- Collect Mature Seeds: Wait until late summer or early fall to harvest seeds from the plant’s woody pods.
- Stratify the Seeds: Carolina Allspice seeds need a period of cold stratification to germinate. Store them in moist sand or a paper towel in the fridge for 60-90 days.
- Sow the Seeds: In early spring, plant the seeds in a well-draining soil mix about ½ inch deep. Keep the soil moist but not soggy.
- Transplant Young Plants: Once seedlings develop a few sets of leaves, transplant them to their permanent location.
Propagating from Cuttings
- Take Semi-Hardwood Cuttings: In mid-summer, cut 4-6 inch sections of semi-hardwood stems.
- Dip in Rooting Hormone: To encourage rooting, dip the cut ends in rooting hormone.
- Plant in a Potting Mix: Place the cuttings in a pot filled with a mixture of perlite and peat moss. Keep the soil consistently moist.
- Provide Humidity: Cover the pot with a plastic bag to maintain high humidity, but allow ventilation to prevent mold.
- Transplant When Rooted: After 4-8 weeks, once roots have developed, plant the cuttings in their permanent home.
