Aubrieta or Rock Cress ( Aubrieta cultorum ) is a low growing, perennial ground cover that originates from the southern mountains of Europe. It is an evergreen; however, it can die back in extreme heat or cold, but will quickly recover once the weather allows. The Genus’ name ‘Aubrieta’ is often misspelt as ‘Aubretia’ and many people commonly know and refer to it this way.
Aubrieta cultorum is truly beautiful when in full bloom during spring and grown in rock gardens or cascading over a garden wall. It is great for attracting bees and other beneficial insects to the garden in early spring. The blue coloured flowers of the species are what is available for sale in this listing.
Another common name for this species is False Rock Cress.
Our other Aubrieta varieties include Purple, Pink and Mixed.
Growth
This species is a perennial in cold to temperate climates but can be grown as an annual in tropical climates. Aubrieta cultorum is a low growing plant that only reaches heights of around 5-10 cm’s and will cover an area of around ½ a metre.
The leaves are green all year round and its gorgeous tiny blue flowers create a blanket of blue from very early in spring. The plant prefers a full sun location but is happy in part shade, especially afternoon shade in areas with extreme summer heat. Quite drought tolerant once established.
Prune back in autumn – winter to encourage next seasons growth and keep the plant neat and tidy.
