Formerly known as Belamcanda chinensis, it is a perennial with bladelike leaves growing from yellowish-orange rhizomes. Flowers in terminal cymes at ends of branches, 1½ to 2½ inches across. Each flower remains open for only a single day. Leaves are nearly identical to those of the garden iris, long and broad. Fruit a pear-shaped capsule about an inch long, that splits open and withers, revealing shiny black seeds, looking very much like a blackberry. The seeds remain attached for many weeks. 
After cold treatment, sow the seed ¼” deep in warm soil (indoors in pots 6-8 weeks before planting outside or in the garden after the danger of frost has passed). Keep the seedbed evenly moist and germination should occur in 1-2 weeks. Will self-seed.
