About Alpine pennycress

Noccaea caerulescens, commonly known as alpine pennycress or snow grass, is a small perennial plant from the Brassicaceae family, valued for its delicate white or pale lilac flowers and compact foliage. It's an excellent choice for rock gardens, alpine gardens, or as ground cover in cool, well-drained areas, adding a subtle touch of color and resilience to harsh environments.

Native range

Europe, Northwest Africa, and Southwest Asia

Care tips

It requires full sun to partial shade exposure and very well-drained soil, preferably calcareous or neutral, avoiding waterlogging at all costs. Although drought-tolerant once established, it appreciates moderate watering during dry periods. A common mistake is planting it in heavy or clay soils, which leads to root rot. It is quite cold-hardy and does not require much fertilization.
