Gypsophila is the Latin name for the flower commonly called baby's breath. This is the delicate white plant often interspersed with rose bouquets and other flower arrangements. There are both annual and perennial gypsophila varieties. The blooms vary in colour from white to extremely pale pink, and the plants grow up to 18 inches tall. They do best in full sun and well-drained soil. Perennial varieties are hardy throughout U.S. Department of Agriculture zones 3 to 9. Gypsophila seeds can be sowed in the garden, after there is no longer a threat of spring frost.
Loosen the soil at the planting site 5 to 6 inches deep.
Plant the gypsophila seeds 1/16 inch deep. Water carefully, just until the soil feels lightly moist. The seedlings will emerge in 10 to 20 days.
Spread a 2-inch layer of mulch under the plants when they are 3 to 4 inches tall. This protects the roots and reduces the need for weeding.
Keep the soil evenly moist, but not soggy, at all times.
Feed perennial varieties with organic fertiliser, applied at half the recommended strength, in early spring. Feed annual gypsophila once every two weeks with water-soluble fertiliser. Apply in the amount instructed on the fertiliser package.
Cut off spent flowers as necessary. Prune the foliage of perennial varieties back to soil level in very early spring.
Gyspophila is an ideal choice for areas with a large deer population, as the animals aren't particularly fond of this plant.
