General Culture:
Bulbs are easily grown in organically rich, moist, well-drained soils in full sun to light shade. North of Zone 8, plants are usually grown in large containers and brought inside in winter. Plant bulbs in a pots/containers that are at least two inches larger in diameter than the bulbs. Bulbs like to be pot-bound. Set bulb in pot with the neck exposed. Keep soils moist and fertilize regularly during growing season. After bloom, reduce watering so that soils dry out between waterings. Bring containers inside in fall before first frost for overwintering in a cool, dry, frost-free location. Propagate by bulblets in spring. Increase watering in spring as plant shows signs of new growth. Although plants can technically be grown in the ground in St. Louis by planting the bulbs in late spring and lifting them in fall in somewhat the same manner as for dahlias, this is generally not considered good practice because crinum roots do not like to be disturbed and once disturbed plants may not bloom for another 2-3 years. It should be noted that some gardeners have been able to successfully grow crinum hybrids year-round in the ground as far north as Zone 6 with a good winter mulch and protected location, however the risk of loss is ever present. When grown in the ground year-round in southern gardens, it will spread by rhizomes to form large colonies.
Noteworthy Characteristics:
Crinum lily is a tender perennial bulb in the Amaryllis family. Lily-like flowers (to 4?wide and long) bloom in clusters in summer atop leafless scapes (to 3-4?tall) above a clump of strap-shaped green leaves. Flower colors in whites, pinks and reds. Most flowers are fragrant. Crinum bulbs are large and taper into elongated necks.
