Perennial in zone 4-9, Rock Cress flourishes in full or partial sun, adding color and texture to landscape borders, rock walls, containers, and rock gardens. Its early, long bloom makes it an excellent choice to grow alongside spring annuals. Prolific blue flowers and evergreen foliage also make an exceptional ground cover. Grow Purple alongside Cascade Red and Cascade Blue for striking color contrast.

General Growing Tips For Your Seedling Tray
For best results with Cascade Purple, plant one rooted liner per 4-inch or gallon container. Use a well-drained soil in full sun with a pH of 5.5-5.9, light feed (75-125 ppm), and an EC of 0.9-1.3 mS/cm (SME) or 1.4-2.0 mS/cm (PourThru). This plant requires bulking and vernalization. Follow 5-6 weeks of bulking at 64-66 degrees with 6-10weeks of vernalization at 40-50 degrees. Vernalization should occur when foliage fills 1/2 to 2/3 of the pot diameter. Use low feed when entering and during vernalization. Aubrieta is day-neutral and does best with 6,000-8,000 fc light. Finish in daytime temperatures of 66-68 degrees and night-time temperatures of 58-60 degrees. Finishing time for a 4-inch container is 14-18 weeks, or 26 weeks including bulking and vernalization. Plant rooted plugs in final containers in mid-fall for spring sales, doing the bulking and vernalization process throughout the fall and winter. Provide sufficient airflow to prevent pythium root rot and botrytis. You may see aphids.
Flowering
Purple flowers bloom from March through May.
Pinching
This plant doesn't require pinching.
Spacing
Space containers for adequate airflow around the base and foliage of each plant to help prevent pythium and botrytis.
Height Control
Cascade Purple doesn't typically require PGRs. Spray B-Nine at 2,500-3,750 ppm if needed to control height.
Pests
You may see aphids.
Disease
Cascade Purple can be prone to pythium root rot and botrytis , especially while the days are short. These diseases are usually associated with wet or humid conditions. You can prevent disease by allowing the plant to dry out between waterings, providing good airflow in your greenhouse, and spacing containers to allow the sun to penetrate to the soil level. The most common chemicals used to treat botrytis are Medallion and Banrot. Use them as a drench according to each label’s instructions.
Planting Cascade Purple Liners
We recommend planting one or two rooted plugs per 4-inch or gallon container. Plant the plugs in the middle of the container in well-drained soil and be sure to completely bury the ellepot.
Rooted Cuttings
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.

Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
