Vegetative/Mat Formation
Several months to 1 yearLow-growing mats of gray-green foliage develop; dense cushion-like growth pattern becomes apparent.
Ensure excellent drainage. Minimal fertilizer needed; avoid nitrogen-heavy feeding. Water only when soil is quite dry. Protect from winter wet in regions with heavy rainfall.
Flowering
4-6 weeks (spring)Delicate white or pale pink four-petaled flowers bloom in clusters above the foliage, creating an airy, dainty display.

Fun Facts
- 🌱 Arabis sturii is named after its native habitat in the Styria region of Austria, where it thrives on rocky Alpine slopes at high elevations.
- 🌱 The genus Arabis belongs to the Brassicaceae family—the same family as cabbage, mustard, and watercress—and all members share the characteristic four-petaled flower structure.
- 🌱 This plant is extremely frost-hardy and can survive temperatures well below freezing, but is far more susceptible to death from excessive winter moisture and poor drainage than from cold.
