Helping You Become a More Successful Gardener
The brilliant violet-purple blooms of purple rockcress will add grand color to any sunny border in need of a boost. 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 glowing flowers and play beautifully against its fuzzy green mats of foliage. Purple rockcress originates from regions in the eastern Mediterranean to Iran where it is adapted to alpine areas.
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. It looks great interplanted with short species tulips, like the raspberry pink Tulipa humulis, brilliant 'Lilac Wonder' and golden apricot Tulipa batalanii.
