WaterThe Rock Cress should be watered moderately, aiming for consistently moist but not waterlogged soil. During the growing season, water when the top inch of soil feels dry to the touch, which typically means once a week. However, this can vary depending on weather conditions and soil type. In hot, dry periods, watering may need to be increased. A good practice is to provide the plant with about one gallon of water every week or two, adjusting as necessary for rainfall and temperature changes. Overwatering can lead to root rot, so ensure adequate drainage and reduce watering in the winter months when the plant is dormant.
LightRock Cress thrives best in full sun to partial shade. The ideal spot for the plant would be an area that receives at least 4 to 6 hours of direct sunlight daily. While the plant can tolerate some shade, too much will diminish flowering and can lead to leggy growth. Ensure the location is protected from harsh afternoon sun in hotter climates to prevent scorching of the foliage.
TemperatureRock Cress is hardy and can withstand a range of temperatures, but it flourishes best in conditions between 50°F and 75°F. The plant can survive minimum temperatures down to 20°F and can handle brief periods of frost. To ensure robust health and optimal blooming, keep it within the ideal temperature range as much as possible, avoiding prolonged exposure to extreme heat or cold.
PruningPruning Rock Cress is essential for maintaining a tidy appearance and encouraging dense growth. After the plant has finished blooming, lightly trim back the spent flowers to promote a second bloom and prevent the plant from getting leggy. Pruning is most effective when done annually in early spring or immediately after the first flowering. This will also help to invigorate the plant for the coming season.

Life cycleAubrieta 'Ida', commonly known as Rock Cress, begins its life cycle as a seed that germinates in cool temperatures, usually in early spring or late winter. The seedling quickly develops into a low-growing, mat-forming perennial with small, oval-shaped leaves. Flowering occurs in mid to late spring, showcasing a profusion of small purple, blue, or pink flowers that attract pollinators. After blooming, the plant sets seed, which can scatter close to the parent plant or be dispersed by wind or wildlife. During the summer months, Aubrieta 'Ida' enters a period of vegetative growth where it can expand its foliage and root system. As winter approaches, the plant's growth slows down, and it may become semi-dormant, relying on its evergreen leaves and robust root system to survive through cold weather until the cycle restarts with the next season's warming temperatures.

Spring-Early Summer
The Aubrieta 'Ida', commonly known as Rock Cress, is typically propagated through cuttings, which is the most popular method for this plant. To propagate Rock Cress, take stem cuttings in late spring or early summer when the plant's growth is most vigorous. These cuttings should be about 2 to 4 inches (5 to 10 centimeters) long and include several sets of leaves. Remove the lower leaves and dip the cut end in rooting hormone for better chances of success. Then, insert the cutting into a pot filled with a well-draining soil mixture. Ensure the cutting is kept moist and placed in a location with indirect sunlight. Roots usually develop within a few weeks, after which the new Rock Cress plants can be transplanted to their permanent location.
