Nearly evergreen
leaves are 1-3 inches long and are covered with
a whitish pubescence. They are tufted in basal
rosettes or borne alternately on prostrate
stems. The tufted basal leaves are usually
egg-shaped, with the wider end toward the apex
and the narrow end tapering to the base. The
stem leaves have extended, rounded (auriculate) or pointed (sagittate)
basal lobes. The leaves may be entire (without lobes or
teeth) or slightly lobed or coarsely toothed toward the

- Arabis alpina
- Alpine Rockcress may be
distinguished from Rockcress by its slightly less
pubescent leaves, its smaller, more compact
growth habit and its shorter flower petals
- Arabis procurrens
(may be listed as Arabia mollis) - easily distinguished
by its
stoloniferous growth habit and its
glossy, dark-green leaves that are slightly
pubescent only on the margins and
undersides. The foliage forms tufted mats
that are only 1-2 inches tall. The flowers
rise above the foliage on leafy stems 10-12
inches tall.
- 'More Pleno' - double-flowering form -
showier flowers that last for a longer
period of time.
- 'Spring Charm' - rosy pink flowers. There
is also a variegated foliage form (the leaves are
margined with creamy white), but this plant tends to
revert to the normal foliage coloration of the species.
