Cuthbert's onion is a perennial bulb in the lily family (Amaryllidaceae) native to SC, AL, FL and GA and found in longleaf pine sandhills. Piedmont and rocky outcroppings. The Genus name is Latin for garlic. Cuthbert's Onion is more heat-tolerant than nodding onion and grows in poor and rocky soils or soils with good drainage in full sun to partial shade. It blooms in May-June with clusters of white, pink or lavender flowers and then dies down in the summer. It can be identified by the bulb that has cross-hatch fibrous scales and the flowers that have a crested ovary and capsule. This bulb is not generally found for sale. The plant could be used in small groups, naturalized areas, rock gardens and borders. Insects, Diseases, and Other Plant Problems: No significant problems. Bulb rot can occur in wet soils. VIDEO Created by Elisabeth Meyer for "Edibles, Bulbs, and Houseplants," a plant identification course developed in partnership with Longwood Gardens.
