Blackberry Lily (Iris domestica): Exotic Blooms and Fascinating Seed Pods

Blackberry lily (Iris domestica, syn. Belamcanda chinensis)—also called leopard lily—is a short-lived perennial from Japan, China, and eastern Russia. Its iris-like fans of sword-shaped leaves support branched stems bearing 2-inch flowers: typically yellow-orange with crimson spots, though solid yellow or near-crimson forms exist.

Growing Conditions

• Zones: 4–10 (containerize in coldest zones)
• Sun: Full sun to part shade
• Soil: Well-drained, average fertility
• Height: 18–36 inches
• Bloom: Mid-to-late summer, several weeks

Unique Features

Flowers last one day but open sequentially. Stems may flop—staking helps. After bloom, tan seed pods split to reveal shiny black seed clusters resembling blackberries (hence the name). Pods persist into winter and excel in dried arrangements.

Taxonomic Note

Long debated, it's now classified in Iris based on rhizome structure and DNA. The specific epithet domestica reflects ancient cultivation.

Propagation

Divide rhizomes in spring or fall. Self-sows modestly. Seed-grown plants bloom in year two.

Design Uses

Mixed borders, cottage gardens, gravel gardens, meadow plantings. Combines well with ornamental grasses, coneflowers, and salvias.
