I'm not sure what it is but I want a bigger plant with these heuchera then the plugs provide. I'm just getting tiered of babying them for 2 years, even then they still seem less vigorous than a full grown plant from the nursery. I meant to collect seeds from my heuchera to sow this year but sadly life got busy and I didn't get to it. The ones that I grew a few years ago from my seeds are mostly still nice plants. However just not as showy as the commercial hybrids. One new one that I would love to buy is Champagne, love the color on that one. Kind of reminds me of 'Ginger Ale' , hope one of the locals around here will sell it.
Cinta, good luck with 'zipper'. Keep us posted on how it does.
