Propagation
Propagate by seed, or by division of rhizomes after flowering; for more advice, see dividing irises
Growing
Grow in very well-drained soil, in full sun, and with the top surfaces of the rhizomes exposed so that they get baked in summer sun, which encourages flowering; best grown in a bulb frame in containers using gritty, free-draining compost, and kept dry during late summer and winter; may be grown outside in a well-drained sunny site on a bank or in front of a sunny wall, if given protection from heavy winter rain
