Annual baby's-breath, a cousin of the perennial type, produces similarly airy sprays of dainty white, pink, or red flowers on wiry stems. They're traditionally used as a delicate filler in fresh and dried bouquets. The tiny gray-green leaves appear in pairs. Forming bushy, upright plants 8 to 24 inches tall, annual baby's-breath elegantly fills voids in the front to mid-portion of flower gardens and can be used in rock gardens and containers.

Notable Varieties
'Covent Garden' is a white-flowered, 18-inch-tall variety.
'Crimson' is bright crimson and 24 inches tall.
'Giant White' has larger flowers on plants 18 inches tall.
'Gypsy' is 12 inches tall and bears semidouble light pink blossoms.
'Rose' bears pale rose flowers and grows 24 inches tall.

Care
Needs excellent drainage and alkaline soil (add lime if soil is acidic). Full sun in cooler regions; partial shade in hot regions. Set up mesh or low cages around the plants for support.The life cycle of annual baby's breath is brief, only five or six weeks -- so you need to resow every couple of weeks if you want continuous bloom.

Planting
Plant nursery plants after frost, or sow in the garden every two to four weeks from early to mid-spring, spacing 12 inches apart. Or start indoors in peat pots four or five weeks earlier at 70 to 80 degrees F. In mild-winter areas Zones 8 and 9, you can also sow in fall.
