Thanks for the effort Lisa. While I like epi's, I don't know what I would do with 30 plants, let alone 60. Same for the callas. I just don't have that much sunny space... yet.
I'm thinking in a few years, the whole back is going to change as old trees (100+ years) are removed. I was looking at the progression of shadows for 2 trees that may have to come out this year. I may actually be able to grow grass in the back yard next year. Oh, wait, there's still the 'crappy soil' thing going on.
