Harvest Tips
Crinum lilies are ornamental flowers best enjoyed in the garden or cut for arrangements. Cut flower stems when the first blooms open; flowers will continue opening. Stems last 1-2 weeks in a vase with fresh water. For seed collection, allow seed pods to mature on plant, then harvest and dry seeds. Bulbs can be divided every 3-4 years in spring for propagation.
