Lactiflora

Lactiflora is a botanical epithet used in plant nomenclature, most notably associated with Paeonia lactiflora, the Chinese peony. The term is derived from Latin and broadly refers to pale or milk-colored flowers in some plant forms. Paeonia lactiflora is a herbaceous perennial in the family Paeoniaceae and has become one of the most widely cultivated peonies for ornamental use.

Paeonia lactiflora is native to central China and has been grown in temperate gardens for centuries. It forms clumps of tall, divided leaves and produces large, showy flowers on sturdy stems. Flower colors range from white and pale pink to deeper pink or rose, often appearing in late spring to early summer. Many cultivars are valued for their long-lasting blooms and, in some cases, pleasant fragrance.

Cultivation requirements are typical of temperate garden peonies. The plant prefers full sun to light shade and rich, well-drained soil. It tolerates cold winters and benefits from a period of chill, which helps flower set. Deeply planting the crown is discouraged; actually planting with crown just above soil level is recommended. Dividing clumps every several years helps maintain vigor. Paeonia lactiflora is hardy in USDA zones 3–8 and may require staking for heavy flowers.

Etymology: lactiflora combines Latin roots meaning “milk” and “flower,” alluding to pale-toned blossoms in some forms. In horticulture, lactiflora also appears as a cultivar epithet within Paeonia lactiflora, contributing to a wide range of modern garden varieties.
