Softly hued blooms with ruffled petals and a bright boss of golden stamens give this compact perennial a refined, harmonious look. Semi-double flowers measure 1½" across and appear from late spring and continue for months, especially with regular deadheading. Neat mounds of scalloped, heart-shaped foliage reach up to 20" tall. Unbothered by deer and rabbits, the nectar-rich blooms bring steady pollinator activity to the garden. Varieties are not individually labeled.
