Hi Jackie, I saw some at McCue's in Woburn, right down the street from Mahoney's in Winchester. And they were the variety 'Illumination' which I grew last year and enjoyed. Not sure they still have them, but I believe they were in the back greenhouse where all the plants for pots are kept.

I used to see it everywhere in Denver....my fav shade perennial and I have never seen it for sale around our area. And if they do sell it, it's probably a single plant for $6 but I don't frequent nurseries where $$ is that high. I find the lack of 4-6 packs of annuals strange...and a rip off. Maybe get some seeds going next year?
