Gardeners' Notes:


On Aug 29, 2013, ms_greenjeans from Hopkins, MN (Zone 4a) wrote:

Regina is the coral bells that I plant for its flowers. I have three on a hillside that have been blooming nonstop from late May to late August, and they show no signs of slowing down. The flowers are a bright pink, almost red. This heuchera can take sun, drought, heat, shade, whatever you throw at it. I have at least a dozen heuchera varieties in my yard, and if I could only choose one, this would be it.
