We have trialed a number of achimenes for winter hardiness and are always thrilled when we find another cultivar to add to our list. Achimenes 'Harry Williams' was a delightful surprise when it returned in great shape after a winter low of 8 degrees F. Emerging in June, the fuzzy green foliage adorns short stems, topped in summer with beautiful pansy-shaped flowers that emerge crimson red, then morph to crimson violet, both with a contrasting yellow throat.
