Crinum lilies are large, heat and moisture loving plants, producing an abundant array of showy flowers in summer. Grown in gardens of southern plantations; many still exist in those areas, overtaken by swamps and bogs. The crinum plant is often referred to as the southern swamp lily, spider lily or as a cemetery plant, indicating it was often used to adorn graveyards of centuries past.
Regaining popularity in the landscape, crinum is usually started from large bulbs, although growing plants can be found in nurseries as well. The crinum plant can also be grown from the large seeds it produces or by offsets called pups. The crinum plant reaches 3 to 5 feet at maturity and the same around. Foliage is spirally arranged, coarse and open. It is often used for a short, growing hedge where blooms and fragrance can be enjoyed. Locate crinum lilies in groups, spacing plants 4 to 6 feet apart. The coarse, draping foliage may appear unkempt, at which time the crinum plant can be trimmed, removing bottom leaves for a tidier appearance.
