Rock cress Aubrieta Axcent Light Blue = 'Abrz0002' (PBR) (Axcent Series)

Water

For the false rock cress, adjust watering to maintain a consistent level of moisture without waterlogging the soil. Generally, this means watering it once or twice a week, depending on weather conditions and soil drainage. In hot, dry periods, watering frequency may need to be increased. A good method is to provide a deep watering that moistens the entire root zone, which equates to about one gallon of water per square foot, every week during the growing season. Cut back on watering in the fall as the plant prepares for dormancy, and over winter, water only sparingly, if at all, to prevent root rot.

Light

False rock cress thrives best in full sunlight, receiving at least six hours of direct sunlight daily. It can tolerate some partial shade, but the blooms may not be as prolific. The ideal spot for planting false rock cress would be in a south-facing garden location that provides ample sunlight throughout the day.

Temperature

False rock cress is tolerant of a wide range of temperatures and can survive minimum temperatures down to about -20 degrees Fahrenheit, making it suitable for many temperate climates. Its ideal growing conditions are in areas where the temperature averages between 60 and 75 degrees Fahrenheit. Excessive heat can stress the plant, so providing some afternoon shade in regions with hot summers can be beneficial.

Pruning

Pruning false rock cress helps to maintain its shape and promote denser growth. Prune lightly after flowering to remove spent blooms and encourage a second flush of flowers. Annually, after the last frost in spring, cut back the foliage by about half to rejuvenate the plant. The best time for major pruning is early spring or immediately after the plant finishes its main flowering period.

Cleaning

As needed

Soil

The best soil mix for Rock Cress (Aubrieta) is a well-draining mix with compost, loam, and gritty material like perlite or sand. A slightly alkaline to neutral pH of 6.5 to 7.5 is ideal for Rock Cress.

Repotting

Rock Cress, typically growing as a ground cover, rarely requires repotting. If grown in containers, repot every 2-3 years or as the plant outgrows its pot.

Humidity & Misting

Rock Cress prefers outdoor conditions with low to moderate ambient humidity. It is tolerant of a wide range of humidity levels as long as there is good air circulation.

Suitable locations

• Indoor

  Ensure full sun, limited watering, and well-draining soil.

• Outdoor

  Plant in full sun, light soil, water sparingly; tolerates dryness.

• Hardiness zone

  4-9 USDA

Life cycle

The plant Aubrieta Axcent Light Blue, commonly known as Purple Rock Cress, begins its life as a seed that germinates in early spring, requiring well-drained soil and some light for optimal growth. After germination, the plant enters the vegetative stage where it develops a low, mat-forming habit with small, oval-shaped, green leaves. As it matures, typically within a few weeks, it enters the flowering stage, producing a profusion of light blue flowers that attract pollinators and provide a vibrant display in rock gardens and along garden borders. After flowering, which usually occurs from mid to late spring, the plant sets seed, completing its annual reproductive cycle, and the seeds are dispersed to give rise to new individuals. Post-flowering, Aubrieta Axcent Light Blue enters a period of dormancy during the colder months, with foliage that often remains evergreen in milder climates. The plant can live for several years, re-sprouting from the base and continuing its life cycle, and can also be propagated through softwood cuttings or division in the spring or autumn.

Propogation

• Propogation time

  Early spring

• The most popular method of propagating the Aubrieta Axcent Light Blue, commonly known as the Rock Cress, is through cuttings. This process typically occurs in late spring or early summer when the plant's growth is most vigorous. To propagate through cuttings, select a healthy stem with several leaves and cut a 3- to 4-inch segment using a sharp, sterilized pruner. Remove the lower leaves to expose a clear section of stem and then dip the cut end into a rooting hormone powder. Insert the cutting into a well-draining soil mix, water gently, and cover with a plastic bag to retain humidity. Keep the cutting in indirect light, and ensure the soil remains moist but not waterlogged. Roots usually develop within a few weeks, after which the new plants can be transplanted to individual pots or outdoor locations.
