An old form called Hose-in-Hose, the calyx has developed to look like petals, and so it appears that one flower is springing from another. It is a pale butter yellow, and is vigorous, hardy and long-blooming. Blooms in April/May. 10”. Culture: Grow in light shade and a fertile well-watered soil. In cool climates, full sun is acceptable if the soil is moist. If too hot and dry, the plants will yellow and go dormant over summer, but usually leaf out again in fall. Best suited to northern climates, it could well be difficult for southern and western gardeners to keep them happy. Propagate by division after flowering.
