Ice Follies Daffodil, a large-cupped daffodil, is one of the most popular mainstays of the spring garden. The large flowers with icy-white petals surround a flat-frilled chartreuse-yellow crown that magically turns white. These beautiful blooms often last for up to 4 weeks. This variety is a great naturalizer and forcer. Royal Horticultural Society, Award of Garden Merit.
