There are various historical gardens scattered across the US...I might look and see if there is one near me. I was in search of one daylily called "Signal" (by Kraus) and I found out that a Historical Garden in NC has it, but they don't have a picture posted. I think it would be neat to find a local Historical Garden and photograph their cultivars for them (and post them to ATP to update the database). I think that will be a goal of mine next season.
