Most of the horticultural admiration for shredded umbrella plant is for its leaves, but I think the inflorescence has a certain charm as well.
There are seven recognized species of Syneilesis; all are native to eastern Asia. Three of China’s four species are endemic, with only Syneilesis aconitifolia (illustration) occurring elsewhere (Korea, Japan, and the far east of Russia). Asteraceous relatives of Syneilesis include Petasites, Doronicum, and Senecio.
Syneilesis aconitifolia is relatively new to cultivation in North America, but established enough to have an entry in Missouri Botanical Garden’s Plant Finder: shredded umbrella plant. Growing characteristics and attributes have also been evaluated through the Trial Gardens at the University of Georgia: Syneilesis aconitifolia. In brief, this species can handle full sun to full shade, with a preference for partial shade and consistent soil moisture. It may become colony-forming.
