Gaura thrives in full sun, ideally six or more hours per day. It can tolerate a bit of afternoon shade in very hot climates, but too little sun will reduce flowering. 

It prefers light, well-drained soil—sandy, chalky or loamy. Avoid rich or waterlogged soil which can cause floppy stems or root rot.

Water regularly in the first growing season. Once established, it becomes quite drought-tolerant—just water deeply during dry spells. Overwatering is more harmful than underwatering.

Generally, Gaura thrives in lean soils and needs little or no feeding. Too much fertiliser, especially nitrogen-rich, can result in spindly, floppy growth.

Deadheading helps prolong blooms, though faded flowers often fall naturally. Prune in summer to encourage fresh growth, and cut back in late autumn or early spring to tidy the plant and prepare for winter. 

When should I divide or propagate it?
Gaura is best propagated by cuttings rather than division due to its long taproot. It self-seeds easily, so you can also let it reseed or lift seedlings in spring. (Epic Gardening)

Is Gaura drought-hardy?
Very much so. Once established, it's highly tolerant of heat and dry conditions and ideal for low‑water areas like borders and gravel gardens. (Homes and Gardens)

What pests or diseases affect it?
It’s generally pest-resistant, though occasional aphids, whiteflies, or powdery mildew may appear in humid or overcrowded spots. Ensure good airflow, and treat infestations promptly. (gardendelivery.com)

How big does it grow and when does it flower?
Most varieties reach around 90 cm tall and 60 cm wide. Flowering typically runs from early summer through autumn, providing long-lasting visual interest. (BBC Gardeners World Magazine, Homes and Gardens, RHS)

Is it perennial in cooler climates?
In milder areas, Gaura behaves as a perennial. In colder regions, it may die back in winter and is often grown as a half-hardy annual or with winter mulch for root protection. (Better Homes & Gardens)
