Dark-colored foliage provides a perfect background for the bright yellow-orange flowers beginning in July. This nonhardy bulb can be grown in either moderately moist to very moist soils in full sun and moderate fertility. In the Chicago region, this plant is not susceptible to some of the foliar pests found in warmer climates. Lift the tubers in fall after the first hard frost and store in a cool, dry environment nestled in wood shavings over the winter. Plant them out in the garden after the soils have warmed (typically the first week in June).
