White Gaura

Gaura lindheimeri 'Sparkle White'

The Story

Plant Bio

Oenothera lindheimeri is a clump-forming herbaceous perennial native to the south-central United States, characterized by its airy, wand-like flowering stems. The species produces narrow, lance-shaped green leaves and loose terminal racemes of four-petaled flowers that flutter in the wind like butterflies.

'Sparkle White' is a compact, highly uniform cultivar that grows to a tidy height of 12 to 28 inches. It produces pure white flowers from pinkish buds that bloom continuously from late spring until the first hard frost.

Uses & Benefits:

Ornamental UsesProvides a delicate, airy texture with pure white flowers that bloom continuously from late spring to frost.
Practical UsesOffers exceptional drought tolerance once established due to its deep taproot system.
Ecological BenefitsAttracts and supports native bees, butterflies, and other beneficial insect pollinators.

Planting

How to Grow

  1. Select a planting site that receives full sun to ensure strong stems and maximum flower production.
  2. Amend heavy soils with coarse sand or gravel to guarantee rapid drainage, as wet winter soils cause root rot.
  3. Dig a hole twice the width of the root ball but equal in depth to prevent burying the crown.
  4. Water thoroughly immediately after planting to settle the soil, then reduce watering once the taproot establishes.

Pro Tip

Plant in sharply drained, sandy or gravelly soil and avoid adding organic compost or fertilizer; rich soils cause the wiry stems to become weak and flop over.

Care Guide

Do

  • Cut back spent flower spikes regularly during the growing season to stimulate continuous blooming.
  • Shear the entire plant close to the ground in late winter to clear dead topgrowth.
  • Plant in poor, well-drained soils to maintain a compact, upright growth habit.

Don't

  • Do not over-fertilize or plant in rich loam, which leads to floppy, weak stems.
  • Do not attempt to divide mature plants, as the deep woody taproot resents disturbance.
  • Do not prune back into old, leafless woody stems that lack active buds.

Common Questions

White Gaura questions

What zones can White Gaura grow in?

White Gaura is hardy in USDA Zones 5–9. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is White Gaura deer resistant?

Yes — White Gaura is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.

When does White Gaura bloom?

White Gaura typically blooms in late spring through fall. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does White Gaura need full sun?

White Gaura does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.

Is White Gaura drought tolerant?

Yes — once established (usually after the first full season), White Gaura handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
