Wall rockcress

Arabis caucasica

Wall rockcress

Forming a pretty mat of flowers in pure white, wall rockcress looks spectacular in early spring. The flowers are so thick they nearly obscure its attractive grayish-green foliage.

An excellent groundcover for tight spots and well-drained soil, it's perfect in a rock garden, along a retaining wall, between pavers in a patio or walk, or along the edge of a raised bed.

Surround columbine with wall rockcress as a groundcover. The white blooms of rockcress set off the blue, purple, maroon, and red shades of columbine.


Low mounds of coral bell foliage mimic the shape of wall rockcress, but its airy spires of pink blooms create a lovely contrast to the low-growing white blooms.


Try wall rockcress interspersed with lungwort in a partly shaded garden. The white of rockcress draws attention to the silvery splotched foliage of lungwort. Pinkish-purple blooms of lungwort top it off.
