Does Aubrieta Grow Back Every Year

The charming cascade of purple, pink, and blue blooms that Aubrieta brings to rock gardens and borders is a sight to behold. Many gardeners wonder, “Does Aubrieta grow back every year?” The answer is a resounding yes, and understanding why this perennial favorite returns with such vigor is key to enjoying its beauty season after season.

The Perennial Promise of Aubrieta

Aubrieta, often called “Rock Cress,” is a hardy perennial plant. This means that once established, it has the natural ability to survive through winter and regrow from its roots in the spring. The plant’s structure is designed for longevity, with woody stems that can persist for years, providing a strong foundation for new growth each year. This perennial nature is precisely why the question, “Does Aubrieta grow back every year,” is met with such positive confirmation. The importance of this perennial characteristic lies in its ability to provide continuous groundcover and seasonal color without the need for annual replanting, saving gardeners time and effort.

Several factors contribute to Aubrieta’s reliable return:

• Dormancy and Root Strength: During the colder months, Aubrieta enters a period of dormancy. Its underground root system remains alive and intact, storing energy to fuel new shoots and flowers when temperatures rise and daylight hours increase.
• Adaptability to Conditions: Aubrieta is known for its resilience. It thrives in well-drained soil, often preferring leaner conditions, and can tolerate full sun to partial shade. These adaptable traits make it less susceptible to environmental stresses that could prevent regrowth in other plants.
• Self-Seeding Potential: While primarily a perennial that regrows from existing root systems, Aubrieta can also self-seed. Small seedlings may appear around the parent plant, contributing to its coverage and ensuring a continuous presence in the garden, even if an individual plant doesn’t perform as expected one year.

To ensure your Aubrieta reliably grows back every year, consider these simple care practices:

1. Pruning After Flowering: A light trim after the main blooming period encourages denser growth and can prevent the plant from becoming leggy. This also helps direct the plant’s energy into developing a strong root system for the following year.
2. Winter Protection (if needed): In very harsh climates, a light mulch around the base of the plant can offer extra protection to the roots during winter.
3. Deadheading: While not strictly necessary for survival, removing spent flowers can encourage a second, albeit smaller, flush of blooms and keeps the plant looking tidy.
