Family

Paeoniaceae

Botanical Name

PAEONIA lactiflora 'Louis Joliet'

Plant Common Name

Herbaceous Peony

General Description

Bearing large, double, deep red blooms early to midway in the peony season, this 1929 introduction is rarely grown today. It is a selection of Paeonia lactiflora, a large, bushy, tuberous perennial from East Asia that has been bred, cultivated, and treasured for thousands of years.

The dome-shaped blooms of this heirloom peony appear on sturdy, medium-tall stems in late spring to early summer. Each blossom has a collar of large "guard" petals surrounding a central mass of ruffled, petal-like segments. Bees, ants, and the occasional butterfly visit the blooms. The bold, divided, dark green leaves turn maroon in fall.

Peonies grow best in full to partial sun and well-drained, fertile soil. These old-fashioned perennials are very long-lived and have been known to survive in gardens for over 100 years. Plant them in foundation plantings or any floral border. Peony blooms make outstanding cut flowers. Although relatively flop-resistant, this cultivar may sprawl if not staked.

Divide plants in early autumn or as shoots break ground in spring. Divide every 3 to 4 years to keep plants vigorous. Plant divisions at a finger's-width depth; plants set too deep will not flower.
