Gauras aren’t just delicate perennials—they’re graceful performers. With their airy wands of butterfly-like blooms and wispy foliage, they bring motion and softness to borders, cottage gardens, and drought-tolerant landscapes.

Whether swaying in a prairie planting, softening a gravel bed, or adding whimsy to a mixed border, gaura offers a long-lasting show of movement, pollinator appeal, and romantic charm that carries from spring through frost.
