Acidantheras need a long growing season, and in zones north of 6 it's a good idea to plant the corms indoors in pots about a month before last frost to give them a head start. Transfer the plants to the garden without breaking the soil balls, or plant pot and all in the garden. Cover plants if fall frosts arrive before flowering stops.
