‘Purple Petticoats’ forms a clump of ruffled, deep greenish-purple leaves, dull purple beneath, with small cream flowers in early summer.
Mount Cuba center trial garden:
“Heuchera ‘Purple Petticoats’ consistently formed dense mounds of purple foliage that fades to dark green. The leaves are highly ruffled which helps to add texture and show off their purple undersides. Its floral display was subpar with greenish-white flowers loosely spaced on very few inflorescences. In 2014, root/stem rot appeared in mid-summer, eventually killing two of the five plants. The other three, however, remained healthy all season. ‘Purple Petticoats’ performed very well in full sun conditions where it only suffered some slight leaf discoloration.”
