Denver Botanic Gardens at Chatfield. A botanical survey was conducted in the mid-1980's by Janet Wingate, Ph.D. of the main Gardens' property. The checklist is currently based on those collections, but Gardens' staff and volunteers are starting a new survey to be completed in 2016, which will include the main property and two satellite sites. New species will be added at the end of each year.
