Blackberry Lily

A perennial herb, I. domestica may grow to a height of 0.6–1 metre (2 ft 0 in – 3 ft 3 in), with its rhizomes in shallow ground, extending horizontally. It has 3-5-stems and 8–14 leaves per stem growing in a fan, with flowers ascending proximally having orange-red scattered spots of darker pigment, blooming during summer. The seed pods open in the fall, showing clusters of black, shiny seeds whose resemblance to those of a blackberry gives the plant its common name, "blackberry lily". The plant is hardy to USDA plant hardiness zone 5 and is propagated by seeds or division. In the wild, it grows in grasslands, pastures, forest clearings, meadows, and mountainous regions or shrublands. Although it has escaped cultivation in many regions, it is not considered to have potential as an invasive species.

The plant is native to Eastern Asia and has been cultivated worldwide in subtropical and temperate climates. Due to the ornamental value of its attractive flowers, the plant was distributed to Europe as early as the 18th century and the United States and Caribbean countries in the 19th century.

I. domestica is a common ornamental plant in private and public gardens, zoos, and floral displays. Its flowers provide nectar and pollen to insects and birds. The plant has been used in traditional medicine.
