H. lilio-asphodelis produces 8 to 12 flowers in spring / early season, about 3 1/2 inches. At 5 1/2 inches, Hyperion's flowers are much larger and appear later, in mid-season. Judy in deliciously cool (67 degrees Fahrenheit) New Jersey, attempting to virtuously get into the ground all the plants sitting in their pots before I go purchase more.
