Heuchera americana ‘Dale’s Strain’

5 Photos


H. americana ‘Dale’s Strain’ is a cultivar originally selected for its exceptional silvery-blue highlights. The silver venation was not identical among individuals but the coloring was remarkably consistent for a seed grown cultivar. It formed a perfect mound of dense foliage which was uniform among all plants. This selection did not flower until 2013, and once it did, its densely mounded habit became more open and spindly. After record rainfall in June of 2013, ‘Dale’s Strain’ began to suffer from root/stem rot and eventually three plants died.  By the end of summer 2014, one of the two remaining plants was also showing signs of root/stem rot. When grown in full sun, ‘Dale’s Strain’ experienced mild burning during the summer months, and thus is only recommended for part shade – full shade conditions.
