Varieties

Ornithogalum umbellatum

(Star of Bethlehem) Choose a sheltered location with well-drained soil that gets full sun to partial shade. Space bulbs 2-5" apart and 4" deep in clumps of 5 or 7 bulbs. Dig bulbs and store indoors in cold winter areas. Grows 36" tall. Blooms late spring-early summer. Hardy in zones 7-10.

Oxalis

(Wood Sorrel) Plant in spring in full sun to partial shade in well-drained soil. Space 2-3" apart and 3" deep. Water well throughout the summer. Grow 6-10" tall. Blooms June-July. Hardy in zones 8- 10. In cold regions, must be dug in the fall and stored in a warm, dry location. Indoor Culture: Plant 1" deep and 2" apart in good potting soil. They need at least 4 hours of direct sunlight per day. Water well and fertilize once a month with indoor plant fertilizer.

Pansies and Violas

(Viola tricolor, Viola x wittrockiana) Usually sold and grown as annuals, but often overwinter dependably. Johnny Jump Ups and Violas (V tricolor) are usually hardier than the larger flowered pansies. Plant in early spring in a part shade location. Only plant in full sun in areas with cool summers. Very frost tolerant and prefers cool, moist conditions. Provide rich, moist well-drained soil. A mulch is often helpful. Deadhead regularly to ensure that plants bloom all season. Hardy in zones 4-8.

Polianthes

(Tuberose) Plant in spring after the weather is relatively warm (60° or more at night). Choose a moist, well-drained, humus-rich location in full sun. Space bulbs 8" apart and 1-2" deep. Feed after the foliage appears. Keep lightly moist. In areas of winter frost, dig the bulbs in fall before the first frost. Store them indoors over the winter. They are very fragrant; avoid planting them near other fragrant flowers; two different perfumed aromas can clash. Grows 24-36" tall. Blooms July-August. Hardy in zones 7–10.

Puschkinia libanotica

(Striped Squill) In fall, plant in well-drained, rich, sandy soil in full sun to partial shade. Plant bulbs 3" deep and 3" apart in clumps of 10-12. Keep well-watered during the growing season. Naturalizes well if not disturbed. Grows 6-8" tall. Blooms April-May. Hardy in zones 3-10.
