Transform your garden into a visual delight with White Rockcress seeds from Sow Right Seeds. These premium seeds produce delicate white blooms that bring a touch of elegance and grace to any outdoor space. Known for their resilience and low-maintenance cascading habit, these perennial flowers thrive as an evergreen ground cover, spilling beautifully over stone walls, edging pathways, or filling planters and window boxes. Beyond its striking appearance, White Rockcress creates a vibrant ecosystem by actively inviting beneficial pollinators like butterflies and bees into your garden season after season.

Sow seeds outdoors directly on the soil surface in full sun, barely covering them, as they require light to germinate. Plant when soil temperatures reach 60–70°F. Space plants 8–10 inches apart to allow room for their spreading habit. Keep the soil consistently moist during germination, which typically takes 14–28 days. Mature plants grow 4–8 inches tall with a spread of 10–24 inches, providing a dense, lush carpet of blooms year after year.

Frequently Asked Questions

Yes, White Rockcress (Arabis alpina) is an evergreen or semi-evergreen perennial in most temperate climates. It maintains a mat of grey-green foliage year-round, offering attractive ground coverage even when it is not actively blooming.

Yes, shear the foliage back by about half its height immediately after the spring flowering period ends. Light pruning prevents the plant from becoming leggy, encourages dense foliage growth, and keeps the mat tidy for the rest of the season.

Absolutely. Once mature and well-rooted, White Rockcress is remarkably drought-tolerant and thrives in lean, well-draining, rocky or sandy soils. Avoid overly damp or waterlogged locations, as excess moisture can cause root rot.

Yes, established clumps can easily be divided in early autumn or right after spring flowering. Gently lift the plant, separate the rooted sections, and replant them in new areas of your garden to expand your ground cover.
