Zantedeschia

(Calla Lily) In frost-free areas, grow calla lilies in a moist, sunny to semi-shady location with soil that has been amended with a lot of organic matter. Plant the rhizomes 4" deep and 12-24" apart. Water liberally and feed monthly during the growing season. After the flowers fade, reduce the amount of water. In areas where Callas are not hardy, allow the plants to dry out. Dig the rhizomes and store in dry material for the winter. Grows 15-18" tall. Blooms June-July. Hardy in zones 9-11. Indoor Culture: Plant one rhizome 1-2" deep in a 6" pot filled with good potting soil. Water lightly and keep in a cool, shaded spot until growth begins. Then move to a sunny window where it can get at least 4 hours of sun a day. Water regularly and fertilize biweekly. Callas thrive in cool temperatures and high humidity. Rest the bulbs for three months after the foliage dies back but do not transplant out of the pot until necessary.

Zephyranthes

(Fairy Lily) Plant in spring in full sun in well-drained, sandy soil. Space bulbs 3-4" apart and 1-2" deep. In areas where bulbs are not hardy, dig them in the fall and store them in warm, dry material for the winter. Grows 8-10" tall, Blooms June-July. Hardy in zones 8-11. Indoor Culture: Plant 5-6 bulbs 2" deep in a 6" pot. Water thoroughly. Keep in a cool, dark area until the foliage emerges. Move to a sunny location with a night temperature of 50°. After the foliage dies, do not water for 10 weeks. To induce flowering, begin the cycle again.
