When growing Gaura outdoors from seed, sow annual varieties just after the last frost of spring. Sow perennial varieties either at the start of autumn or the start of spring. Lightly cover the Gaura seeds once sown.
Ideally the plants should be spaced at about 60 to 90 cm (2 to 3 feet) apart.
Locate in a sunny part of the garden, that has good drainage and an ordinary soil.
If starting off indoors, then sow out seeds about 5 weeks (annuals) or 10 weeks (perennials) in advance.
Gaura germination takes from two to five weeks at a temperature of 18 to 24 degrees centigrade (64 to 75°F).
Transplant annual Gaura varieties out in the garden following the last frost. Transplant perennials in the autumn or just before the last frost.
It is easy to look after Gaura plants, they are naturally from dry areas of central America and can thus tolerate drought. So there is no need to water them.
If you remove spent flowers, the blooming period will be prolonged.
During the second year of growth, it is a good idea to cut back the plant to about 25 cm (10 inches) in height. This will encourage them to branch and become more shrub like.
If you require further plants, then propagate perennial Gaura by division in the spring or autumn.
