A nice, slow growing heuchera. Very pretty foliage. I grow it in zone 4 in a semi-shady spot. Cut the flowers off as they are nothing to look at.

Gorgeous coloration on leaves. Did not divide well in late summer, but overwintered w/o snow cover 2011-2012 and didn't bat an eye. Worth having, but I'm dividing in spring from now on!

A really pretty Heuchera that looks striking with so many color combinations. Blooms in May-October in my garden, but the blooms are pretty insignificant. PP #18551

This is a very beautiful Heuchera that seems to do well in full shade as well as in part sun. A lovely addition to any shady garden. Not an incredibly fast growing Heuchera.

I actually grew this plant in full Oklahoma sun and it didn't flinch. I'm very impressed with how well it grew.
