Gardeners' Notes:

My Miracle has never developed the dark red leaf color, but instead stays looking alot like Electra. I'm wondering if it's exposure impacts the color, as all of mine are in virtually full shade. I think I'll test moving one to a mostly sun location and see what happens....

Very nice Heuchera. Mine handily survived a long, long winter of snow, rain, more snow, rain, etc. More robust than its sister 'Tiramisu' (at least in my garden) and an easier foliage color to work with. Mine never get the very dark bronze shown in some photos. I'll plant more!
