More About Gomphrena ‘Gnome Purple’

Gomphrena ‘Gnome Purple’ is a dependable summer annual prized for its vivid purple, clover-like flower heads that hold their color through intense heat. The papery blooms sit atop sturdy stems and remain attractive for weeks, even in hot, dry conditions where many flowering plants struggle.

This compact selection stays tidy and well-branched, making it easy to use in containers or tight garden spaces. The flowers continue appearing nonstop from late spring until frost, with no deadheading required.

Why We Like It (Our Trials)

In our trials, ‘Gnome Purple’ has been exceptionally reliable during hot, dry summers. It establishes quickly, maintains a neat mounded shape, and continues flowering when other annuals slow down.

We especially appreciate its versatility. It works beautifully in mixed containers, as a front-of-border plant, or in mass plantings where the repeated purple blooms create strong visual rhythm. Bees and butterflies visit regularly, and the flowers are excellent for fresh or dried arrangements.

Gnome Purple’ vs. Other Gomphrena

Gnome Purple is all about restraint, structure, and season-long dependability, offering a compact, low-profile form that stays neat from planting through frost. Compared to Gomphrena Truffula Pink, Gnome Purple remains tight and controlled, making it ideal for containers, edging, and highly designed spaces where scale matters. Its rich purple blooms read as solid blocks of color rather than airy sprays, giving plantings a grounded, intentional look. While Truffula Pink draws the eye upward with height and motion, Gnome Purple works quietly but consistently, filling space without ever overwhelming its neighbors
