Botanical Name

AUBRIETA deltoidea( Variegata Group)

Plant Common Name

Purple Rockcress, Variegated Rockcress

General Description

There are various variegated forms of purple rockcress that fall into this group. This mat-forming, semi-evergreen perennial becomes clothed in flowers in spring to early summer. Its blooming period lasts for an average of three weeks, sometimes even a month. The pretty vivid flowers and play beautifully against its fuzzy green mats of variegated foliage that’s usually edged in cream. The flowers come in an array of colors to include violet-purple, violet-blue, pink and white. Purple rockcress originates from regions in the eastern Mediterranean to Iran.

Sunny locations with fertile, neutral to alkaline, well-draining soil are preferred. It should be watered regularly before and after blooming but can be allowed to get a little drier later in the season. This perennial does not divide easily and is best left alone to spread and flourish. Rockcress is short-lived in gardens with hot summers but thrives in areas with cool or moderate summers. Propagate by seed or cuttings.

This true alpine looks best in sunny rock or alpine gardens, between stepping stones or cascading from chinks in stone walls. They look great interplanted with short species tulips, like the raspberry pink Tulipa humulis and golden apricot Tulipa batalanii.
