Three types of leaves: football, ghost and mitten. Can you find them all in the pics? And beautiful fall color. Just proves that there is always something beautiful at the UC Botanical Garden. I've read that there are only two main species in this genus, S. Tzumu from China, and S. albidum from eastern North America. Main species? Maybe there are subspecies? There is also S. randalense. S. randalense and S. Tzumu are Asian and moneocious. S albidum is dioecious. They are all butterfly host plants. The American one hosts the spicebush butterfly and the Taiwanese one hosts the broadtailed swallowtail.
