Spider lily, known botanically as Lycoris radiata, is a late summer flowering bulb that produces multiple coral red blooms with long, thin spider leg-like petals and stamens atop tall stems. Though called a lily, it is actually a species in the amaryllis family. Spider lily grows best in U.S. Department of Agriculture (USDA) climate zones 7 through 10 when you use mulch in the winter. You can grow it indoors in the winter in colder climates. It thrives in rich but well-drained soil and with at least four hours of full sun exposure daily.
Cut back dying flower stems down to the bottom of the stem just above the crown of the plant between the leaves. Compost or discard them in the trash.
Mulch around the evergreen foliage and bulb roots in the fall in USDA Zones 7 through 10. Use a at least 2 inches of organic material such as compost, shredded bark or leaf mold.
Overwinter spider lily bulbs indoors in USDA Zones 6 and below. Dig, clean and store your bulbs in the clean sand in a low-light location with ambient temperatures between 45 and 55 degrees. Replant in the spring after the last hard frost has passed.
