Calycanthus floridus ’Athens’ (a/k/a ’Katherine’ for Dr. Michael Dirr’s oldest daughter) was first given widespread availability by Cedar Lane Farms in Madison, GA thanks to owner, Jane Symmes and was one of the first plants we acquired (see SKU number) in 1989 when we started our nursery. The clone is unique in the yellow flower color. To some degree it is also unique due to its intense, fruity fragrance since many "sweetshrubs" have no fragrance at all. It’s a plant native to the USA if that matters to you, and its perfume is most noticeable in the evenings. Height to 8 feet and spreading much wider where space allows (a feature of many native shrubs). Always in limited supply since we propagate it by digging suckers from a large patch near our retail area, and I’d rather dig to plant a new specimen than spend much time separating suckers. It’s a great plant. I’m the one that’s lazy. Zones 5 - 9.
