Sweetshrub

Question

How do I grow this plant from seeds

Answer 1

Germinating Carolina allspice (Calycanthus floridus), or sweetshrub, from seeds can be moderately challenging due to seed dormancy. For optimal germination, collect fully ripe seeds and store them in a cool, dry place before planting. Carolina allspice seeds benefit from a period of cold stratification lasting 4-6 weeks to break dormancy; place seeds in a moist medium and refrigerate. Sow seeds in well-draining, fertile soil at a depth of 1/4 to 1/2 inch, and maintain a consistent temperature of 65-75°F (18-24°C) with partial shade. Germination can be slow and erratic, taking weeks to months. The germination rate varies but can be improved by sowing more seeds than needed. Provide careful attention to soil moisture and environmental conditions to support successful seedling emergence and growth.
