Plant Details

Stems rising from leafy clumps bear very fragrant flowers in summer; blooms resemble daffodils in having a center cup, but cup is surrounded by six slender, spidery segments. Deciduous species maintain foliage throughout summer if watered, then die back in fall. Plant in rich, well-drained soilin late fall or early winter in frostless areas, after frosts in other areas. Set bulbs with tips 1 in. below surface; space 1 ft. apart. Deciduous sorts can be dug after foliage has yellowed (do not cut off fleshy roots), dried in an inverted position, and stored in open trays in a cool, dark, dry place. These are pest-free plants; deer, squirrels, and voles won't eat them.

H. caroliniana. SOUTHERN SPIDER LILY. Deciduous. Zones US, MS, LS, CS; USDA 6-9. Native to swampy woodlands of Georgia, Indiana, and Louisiana. Each bulb produces as many as 12 deep green leaves 112 ft. long, 12 in. wide. White flowers to 5 in. across appear in spring and summer, in clusters of two to seven. Multiplies rapidly.

H. coronaria. SHOALS SPIDER LILY, CAHABA LILY. Deciduous. Zones MS, LS; USDA 7-8. Rare species found in a few rocky shoals of rivers in Alabama, Georgia, and South Carolina. Straplike leaves up to 3 ft. long rise above water from bulbs anchored in soil between rocks. Groups of six to nine fragrant white flowers with yellowish centers, to 2 in. across, appear atop 3-ft. stalks from mid-May to early June. Each flower lasts one day. Species endangered by degradation of habitat due to sedimentation; do not collect plants from the wild.

H. eulae (H. galvestonensis). Deciduous. Zones MS, LS, CS, TS; USDA 7-11. Native to Texas and Louisiana. Blue-green foliage appears in late winter, disappears in spring. Flower stems to 20 in. high emerge in midsummer, bearing clusters of six to nine white flowers, each about 5 in. across.

H. x festalis (Ismene x festalis). Deciduous. Zones LS, CS, TS; USDA 8-11. A hybrid of two Peruvian species. Mid-green leaves can reach 3 ft. long. Erect stems hold clusters of 25 fragrant white flowers, each up to 6 in. across. 'Zwanenburg' has larger, fuller flowers with scalloped cups.

H. latifolia (H. keyensis). CAYMAN ISLANDS, SPIDER LILY. Evergreen. Zone TS; USDA 10-11. Native to southern Florida and the West Indies. Clusters of 10 to 16 white flowers, each consisting of a 3-in. cup outlined by spidery segments to 5 in. long.

H. liriosme. TEXAS SPIDER LILY. Deciduous. Zones MS, LS, CS, TS; USDA 7-11. Native from Alabama to Texas. White, exceedingly fragrant flowers to 8 in. across are held in clusters of 8 to 10. Likes wet soil.

H. maximiliani. MAXIMILIAN'S SPIDER LILY. Deciduous. Zones MS, LS, CS, TS; USDA 7-11. From Mexico. Dense clump of slender, glossy green leaves. Each stem bears a cluster of several 6-in., spidery, white flowers in early summer.

H. narcissiflora (Ismene calathina). BASKET FLOWER, PERUVIAN DAFFODIL. Deciduous. Zones LS, CS, TS; USDA 8-11. Leaves 1122 ft. long, 12 in. wide. White, green-striped flowers to 4 in. across are held in clusters of two to five. 'Advance', a hybrid with H. x festalis, has pure white flowers, faintly lined with yellowish green in the throat.

H. 'Sulphur Queen'. Deciduous. Zones LS, CS, TS; USDA 8-11. Primroselike yellow flowers, to 6 in. across, with light yellow, green-striped throats; up to six per cluster. Sweetly fragrant. Leaves are much like those of H. narcissiflora.

H. 'Tropical Giant'. Deciduous. Zones MS, LS, CS, TS; USDA 7-11. Reliable old garden hybrid often found on abandoned properties in the South. Excellent foliage plant, its glossy green leaves forming an impressive clump in the boggy conditions it prefers.
