WaterRock cress, including the variegated 'Doctor Mules' variety, prefers evenly moist soil but does not tolerate waterlogged conditions. You should water these plants when the top inch of soil feels dry to the touch. Depending on weather conditions, this might be approximately once a week, but it's essential to check the soil moisture before watering. An average amount to water might be about 16-24 ounces for smaller plants or up to 1 gallon for larger, established plants in garden beds, ensuring you water directly at the base and avoid wetting the foliage to prevent disease.
LightRock cress thrives best in full sun conditions where it can receive at least 6 to 8 hours of direct sunlight daily. Planting it in a spot that gets ample morning sunlight with some afternoon shade is ideal, especially in hotter climates. However, it is flexible enough to also tolerate partial shade, especially in regions with very intense sun.
TemperatureRock cress is hardy and can withstand temperature fluctuations, growing well in typical garden environments. The plant can survive a minimum temperature of roughly 20 degrees Fahrenheit and can tolerate maximum temperatures that reach well into the 80s or 90s Fahrenheit. Ideally, it prefers a temperate range, enjoying the cooler end of the spectrum, where nighttime temperatures might dip to around 60 degrees Fahrenheit.
PruningRock cress should be pruned to promote bushier growth and to remove any spent flowers or damaged foliage. Pruning is best done right after flowering to encourage a second bloom and to maintain its compact form. Typically, pruning once per year is adequate, removing only a few inches off the top to shape the plant. The best time for pruning is late spring or early summer, immediately after the first bloom.
CleaningAs needed
SoilVariegated Aubrieta prefers well-draining soil with a slightly alkaline pH between 6.5 and 7.5. A mix with grit or perlite and compost or loamy soil works best to provide the necessary drainage and nutrients.

Life cycleAubrieta 'Doctor Mules Variegata', commonly known as Rainbow Rock Cress, starts its life cycle with seed germination, typically in early spring, when soil temperatures warm up. Once the seedlings have emerged, they develop into a low mat-forming perennial, characterized by variegated leaves that provide ground cover. Throughout spring, the plant blooms with small purple flowers, adding color and attracting pollinators to the garden. After flowering, seed set occurs, allowing for dispersal and new plant establishment. As temperatures cool in autumn, the plant may experience a semi-dormant phase where growth slows. Rainbow Rock Cress is a hardy plant that can survive winter conditions, reemerging vigorously the next spring to continue its life cycle.
PropogationPropogation time
Spring to early summer
The most common way to propagate Aubrieta 'Doctor Mules Variegata', commonly known as variegated purple rock cress, is through cuttings. This method is typically done in early summer when the plant's growth is vigorous. Gardeners will select healthy, non-flowering shoots and cut a length of approximately 2 to 4 inches (5 to 10 cm). The cut end is then dipped in rooting hormone powder to encourage root development and planted in a well-draining potting mix. The cutting should be kept moist and placed in a warm, well-lit area but out of direct sunlight until roots establish, which usually takes a few weeks. Once rooted, the new plants can be transplanted into their permanent positions in the garden.
