Rock cress Aubrieta gracilis 'Kitte Purple'
ABOUT
Aubrieta gracilis 'Kitte Purple', also known as rock cress, is a vibrant perennial plant renowned for its colorful springtime display. This particular variety boasts a profusion of rich purple flowers that blanket its foliage. These blooms are small and dainty, with a typical four-petal structure that creates a dense, mat-forming appearance. The petals have a slightly ruffled edge, adding to their charm, and a prominent center that draws pollinators. The foliage of rock cress is equally appealing, with small, oval-shaped leaves that are slightly hairy and have a grayish-green hue. These leaves form a low-growing mound or carpet, which makes rock cress an excellent ground cover. The leaves remain evergreen in milder climates, providing visual interest even when the plant is not in bloom. Rock cress is well-loved for its ability to thrive in rocky, alpine environments or garden settings such as over walls or in rock gardens, where its cascading habit can be fully appreciated. Its dense flowering and evergreen leaves create a wonderful contrast against stonework or other plants, making 'Kitte Purple' a popular choice for gardeners looking to add a splash of color and texture to their landscapes.

WaterRock Cress, commonly known as Aubrieta, requires moderate watering, especially during its growing season in spring and early summer. It’s best to water it when the top inch of soil feels dry to the touch, which typically amounts to once every week or two, depending on climate conditions. When watering, it's important to use a gentle flow to avoid disturbing the soil and roots, aiming for a deep watering that reaches all parts of the root zone. This might equate to about 1 gallon of water for an established plant in a garden setting. Reduce watering in the fall and winter when the plant is dormant.
LightRock Cress thrives in full sun to partial shade. The ideal spot for Rock Cress is one that receives at least 6 to 8 hours of direct sunlight daily, but it can also tolerate some light afternoon shade, especially in hot climates. Avoid placing it in deep shade, as this can lead to poor flowering and leggy growth.
TemperatureRock Cress is hardy and can tolerate a wide range of temperatures but grows best if the temperature stays between 60 and 75 degrees Fahrenheit. It can survive minimum temperatures down to about -20 degrees Fahrenheit and maximum temperatures up to 85 degrees Fahrenheit. However, prolonged exposure to temperatures outside of its ideal range may result in stress for the plant.
PruningPruning Rock Cress can encourage a more compact growth habit and enhance its flowering performance. Lightly trim the plant right after it has finished blooming, usually in late spring or early summer, to remove spent flowers and any leggy growth. An annual pruning like this will help maintain its shape and vigor, avoiding the need for more drastic pruning later on.
CleaningAs needed
SoilRock Cress requires well-draining soil with a slightly alkaline pH, typically between 6.5 and 7.5. A mix of regular garden soil, coarse sand, and compost would serve as an ideal growing medium to ensure good drainage and fertility.
RepottingRock Cress generally does not need frequent repotting as it is a low-growing perennial. Repotting can be done every 2 to 3 years to rejuvenate the soil and manage the spread.
Humidity & MistingRock Cress prefers a drier climate and does not require high humidity. Average room humidity is typically suitable for this plant, as excessive humidity can lead to fungal diseases.
Suitable locationsIndoor
Ensure light exposure and use well-draining soil.
Outdoor
Plant in full sun with well-draining soil; trim after flowering.

Life cycleAubrieta gracilis 'Kitte Purple', commonly known as Kitte Purple rock cress, begins its life as a seed, which, when placed in well-draining soil and given ample sunlight and moisture, will germinate. The seedling emerges and develops a small rosette of leaves at the soil surface; during this juvenile phase, the plant establishes its root system. As the plant matures, it enters a vegetative state, spreading outwards with its evergreen leaves and preparing for the flowering stage. In early to late spring, the Kitte Purple rock cress produces vibrant purple flowers that attract pollinators and are essential for the reproductive phase. After pollination, the flowers develop into seed pods, which eventually dry out and release seeds for the next generation. In the winter or once flowering is complete, the plant may go dormant, reducing its above-ground activities until conditions become favorable again for growth.
PropogationPropogation time
Spring-Early Summer
The Aubrieta gracilis 'Kitte Purple', commonly known as false rock cress, is a perennial plant that can be propagated through several methods, with stem cuttings being the most popular due to its simplicity and effectiveness. To propagate by stem cuttings, choose a healthy, non-flowering shoot in the late spring or early summer. Cut a 3- to 4-inch (approximately 7.5 to 10 centimeters) length from the tip of the stem, ensuring at least a couple of leaf nodes are included. Remove the lower leaves and dip the cut end into rooting hormone to encourage root development. Plant the cutting into a well-draining soil mix, and keep it in a bright, indirect light location while maintaining consistent moisture. With proper care, roots should establish within a few weeks, at which point the cutting can be gradually acclimatized to outdoor conditions.
