Approximately 100% of the plants died by the end of the summer; Those in the most sun bloomed, guess I need to move the others, beautiful foliage, I will use it in purple boutonnieres; 'Velvet Night' was the only heuchera of the two that I thought might have stems long enough for use as a cut flower.
