Grow Calamintha nepeta 'Montrose White' for a long season of delicate, airy bloom and an easy-care habit that fits almost anywhere. This lesser calamint makes a loose, tidy mound with small aromatic leaves, then covers itself in clouds of tiny white flowers over a long summer-to-fall window. You will love how it adds a soft, see-through texture that brightens borders without overwhelming nearby plants.
Give it full sun for the heaviest flowering, but it will also perform well in part shade, especially where afternoons are hot. Plant it in well-drained soil and water regularly the first season to help it establish. Once rooted in, it tolerates dry spells better than many perennials, making it a smart choice for low-input beds and sunny edges.
At maturity it typically stays around 12-18 inches tall, spreading into a broader mound that looks natural in cottage plantings, gravel gardens, rock gardens, and along walkways. The blooms and foliage are both appealing up close, and the flowers are a steady draw for pollinators, including butterflies and hummingbirds.
For simple maintenance, shear or cut back after a flush of bloom to refresh the plant and encourage a clean habit. In late fall or early spring, trim back old stems as new growth begins. With good air circulation it stays healthy and dependable for years.
