Wall Rockcress

Arabis caucasica

Wall rockcress is an outstanding spring-blooming groundcover for dry, sunny spots in Northern gardens. It’s easy to care for and bursts into bloom in spring, producing so many pure white flowers they almost hide the foliage. After it’s finished blooming it sports gray-green leaves that look good for the rest of the season.  

Surprisingly, wall rockcress is in the cabbage family. It’s related to common garden vegetables including cabbage and kohlrabi. It’s also related to a variety of fine spring-blooming flowers, including aubrieta and wallflower.

garden plans for Wall rockcress

Wall Rockcress Ground Cover

Its low-growing nature makes wall rockcress an excellent choice for planting along paths and walkways, where you'll be able to enjoy its floral display up close. Or plant it in the front of the border as an edging plant. It's particularly stunning when mixed with plants that have contrasting foliage, such as 'Firewitch' dianthus.

This easy-care ground cover is also a fine choice for rock gardens and growing with other alpine-type plants including armeria and lavender. Because it roots in as it grows, you can also use wall rockcress on slopes, green roofs, and for planting in pockets between stones in walls. It doesn't take foot traffic well, so it's not the best choice for planting between paving stones.

These are the best plants for rock gardens.

Wall Rockcress Care

For success, it's essential to plant wall rockcress in a spot that has well-drained soil—the faster it drains, the better. That also makes it an ideal pick for gardens that have soil with a high sand content or a lot of gravel. If your soil has a high clay content, plant wall rockcress in a raised bed.

In a sunny spot, this perennial is practically carefree. But lots of bright light is important; in addition to soil that doesn't stay wet for extended periods, wall rockcress demands full sun—at least eight hours of direct light per day. If it doesn't get enough sun it won't bloom well and is more susceptible to root diseases.

Wall rockcress is native to areas of Western Asia and the Middle East. It does best in areas with cool summers. In areas that experience hot, humid summers, the plant tends to melt out and may not survive the end of the growing season.

This perennial is deer- and rabbit-resistant, so you can typically enjoy its springtime color show even if your yard is frequented by these four-legged visitors. It also tends to attract early-season pollinators, including bees and butterflies, to the spring landscape.

Plant Wall Rockcress With:

Columbine
Perfect for cottage and woodland gardens, old-fashioned columbines are available in almost all colors of the rainbow. Intricate little flowers, they are most commonly a combination of red, peach, and yellow but also blues, whites, pure yellows, and pinks; they look almost like folded paper lanterns.Columbine thrives in sun or partial shade in moist, well-drained soil. Plants tend to be short-lived but self-seed readily, often creating natural hybrids with other nearby columbines. If you want to prevent self-seeding, deadhead plants after bloom.
Coralbells
Exciting new selections with incredible foliage patterns have put coralbells on the map. Previously enjoyed mainly for their spires of dainty reddish flowers, coralbells are now grown as much for the unusual mottling and veining of different-color leaves. The low clumps of long-stemmed evergreen or semi-evergreen lobed foliage make coralbells fine groundcover plants. They enjoy humus-rich, moisture-retaining soil. Beware of heaving in areas with very cold winters.
Lungwort
In early spring, the brilliant blue, pink, or white flowers of lungwort bloom despite the coldest chill. The rough basal leaves, spotted or plain, always please and continue to be handsome through the season and into winter. Planted close as a weed-discouraging groundcover, or in borders as edgings or bright accent plants, lungworts are workhorses and retain their good looks. Provide high-humus soil that retains moisture. Although lungwort tolerates dry conditions, be alert for mildew.
