Cream-Flowered Rockcress

Arabis pycnocarpa

Cream-Flowered Rockcress (Arabis pycnocarpa) is an evergreen perennial, grown for its large, fragrant flowers and attractive foliage. This low-growing plant can reach up to 20” tall, featuring creamy-white flowers that bloom from late spring to late summer. Its deep-green leaves are evergreen, creating a backdrop for the flowers. Due to its durability and rough terrain adaptability, Rockcress is often used in rock gardens and alpine gardens. During winter, the leaves may turn purplish, but will return to their normal color come spring. It is deer resistant, drought tolerant, and low maintenance, making it a popular choice for both novice and experienced gardeners.

watering

Western Hairy Rockcress needs regular watering in order to stay healthy and vigorous. New plants should be watered every few days until established when they should be watered with a deep soak, every 4-7 days, depending on weather conditions and soil type. During hot weather, it may need more frequent watering. As a general rule, if the soil is allowed to dry out completely between waterings, the plant will thrive.

sunlight

Western Hairy Rockcress (Arabis hirsuta var. hirsuta) typically prefers moderate sunlight that is neither too direct nor too indirect. For optimal health, the plant should receive full sun in the morning and light shade in the afternoon. Western Hairy Rockcress is best suited for planting in an area that receives at least 4 to 6 hours of sunshine each day. It is also important that it not be planted in an area where it is in deep shade for more than several hours of the day.

pruning

Pruning Western Hairy Rockcress should be done in winter when the plant is dormant. For optimal plant health, it is recommended to prune the plant back by up to a third of its height. When pruning, it is important to make sure all budding stems, leaves, and flowers are completely removed back to the base of the plant. This will ensure that the growth of the plant remains robust in the spring and summer months.
