This variegated rock cress is a unique addition to rock and alpine gardens; also great to grow over walls and trailing along slopes; great in particularly hot spots in the garden
Variegated Alpine Rock Cress is smothered in stunning lightly-scented white daisy flowers at the ends of the stems from early to late spring. Its attractive small deeply cut narrow leaves remain grayish green in colour with showy creamy white variegation throughout the year. The fruit is not ornamentally significant.
Variegated Alpine Rock Cress is a dense herbaceous evergreen perennial with a ground-hugging habit of growth. Its relatively fine texture sets it apart from other garden plants with less refined foliage.
This is a relatively low maintenance plant, and should only be pruned after flowering to avoid removing any of the current season's flowers. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.
Variegated Alpine Rock Cress is recommended for the following landscape applications;
- Rock/Alpine Gardens
- Border Edging
- General Garden Use
- Container Planting
Planting & Growing
Variegated Alpine Rock Cress will grow to be only 6 inches tall at maturity, with a spread of 18 inches. Its foliage tends to remain low and dense right to the ground. It grows at a slow rate, and under ideal conditions can be expected to live for approximately 10 years.
This plant should only be grown in full sunlight. It prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution, and will benefit from being planted in a relatively sheltered location. Consider covering it with a thick layer of mulch in winter to protect it in exposed locations or colder microclimates. This is a selected variety of a species not originally from North America. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
Variegated Alpine Rock Cress is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. Because of its spreading habit of growth, it is ideally suited for use as a 'spiller' in the 'spiller-thriller-filler' container combination; plant it near the edges where it can spill gracefully over the pot. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, most plants cannot be expected to survive the winter if left in containers outdoors, and this plant is no exception. Contact our store for more information on how to protect it over the winter months.
At Dutch Growers, we treat this plant as a "HOBBY PLANT". It is not officially recognized as winter-hardy in our zone 3, however, there is a strong liklihood that it will survive winter. Warranty expires on Nov. 1 season of purchase.
