Herbaceous Peonies

Herbaceous peonies are hybrids with Paeonia lactiflora as a parent. There are more than 4,000 cultivars of herbaceous peonies with flowers in shades of red, pink, white, coral, or butter yellow. The stems of herbaceous peonies die back to the ground every winter; new stems emerge in early April; flowers bloom throughout the month of May, finishing in mid-June; seeds are sometimes produced, ripening in the summer; and plants go dormant in late autumn.
