Gardeners' Notes:

I started this plant from seed (Prairie Moon) in Spring 2013. Although it was tricky, with stratification, I did obtain a few seedlings. Now in June 2014, I have beautiful flowering plants. Also, I planted it in a protected, but not ideal, place. I read that it is unwise to attempt to transplant it, so I will collect seed and see if I can expand my collection. In summary, my experience is that it is a truly lovely plant, well worth the effort to start from seed.

Beautiful stuff! I collected this stuff from under a basswood tree in a cousin's woods, and planted it under another one at home. Once the seedbank built up there was a steady stream of seedlings. The basswood shade is remarkably dense, so the success is about occupying an spring ephemeral niche.

This is a gorgeous native plant. I have a few of the dark purple and a couple of the white with a purplish tinge. Unfortunately, the white ones get lost among the other white flowers in the woodland garden, but nothing beats the deep purple ones for color.

Mine are slowly spreading about. It takes two periods of cold stratification for the seed to germinate, which equals 2 winters for lazy me who just lets them self-seed in the garden rather than enlisting the fridge's help. Plus we've been plagued with drought for a few years which hasn't helped the seedlings survive. The adult plants have thrived regardless.

I live in Oregon, and I have had trouble growing this plant. I just love the look of it, but it does not seem to want to live at my house. My daughter has also trie to grow it at her home also in Oregon, with no luck. Not sure what we are doing wrong.
