Gaura Facts and Info
Gaura lindheimeri grows in Zones 5-9. It has an upright form and a fine texture.

Gaura lindheimeri Care
Plant 24-36” apart in spring or fall. Apply slow-release granular plant food at time of planting. Water deeply when the soil is dry. Even though the plants are low maintenance and drought tolerant, they perform better if watered during dry spells. Apply 3” of vegetative mulch in summer to help retain soil moisture.
The flowers of gaura plants do not need to be deadheaded unless the occasional brown hue is not acceptable. Leave plants standing in fall until they wilt from frost, then prune them back. The foliage can be sheared back in early summer to create a more compact habit. The plants are short-lived, especially in cooler climates, and may need replacing every 2-3 years.
Propagation: Sprinkle the seeds over the soil mix and leave exposed to light, but do not cover them. Thoroughly moisten and keep them moist, not soggy, until the seeds germinate. Germination occurs in 5-12 days at 70-72 degrees. Transplant 20-28 days after sowing. After transplanting, reduce temperature to 50 degrees.
Pests and Diseases: Insect pests include aphids and beetles. Disease pests include rust, leaf spots, and powdery mildew.
