The Trillium Discussion for Enthusiasts has a new online glossary thanks to Jim Shields at Shields Gardens and his cohorts.
Shields Gardens is in Westfield Indiana. Check out the Shields beautiful site here.
The online discussion is over my head most of the time but I joined to learn about Trilliums. The plants in my garden were sent to me by a couple of generous members of the discussion group.
Edgewood Gardens website has lovely Trillium photos.
