Cultivars:


There has been a significant debate on the “trillium list” as how to address trillium cultivars. This debate has centered around formal registration of trillium cultivars. My objective is not to address this debate, but share what information is available on trillium cultivars. I will start with linking you to what I believe to be the most comprehensive trillium cultivar list (CARL DENTON’S LIST). If you know of others please submit them to ... <harold@trilliumresearch.org>.

A second objective is to encourage all to search for the 'best trillium qualities' that you find in native and cultivar trillium and pursue or encourage their propagation for future generation ‘trillium lovers’. This site is available to assist you in sharing such findings and encouragement. Please email your 'Best Trillium Qualities' submittals to ... <harold@trilliumresearch.org>. A picture demonstrating that quality would great (but not required).

Additionally, I offer some proposed glossary definitions to consider when we discuss trillium species, forma, varieties and cultivars.

Proposed Trillium Glossary Definitions
