Wall Rock Cress (Arabis Alpina Rosea) - Wall Rock Cress is grown widely as a rock garden or ground cover perennial. It is treasured for its bright spring display and low-growing carpet of color. Rock Cress seeds produce plants that form a mounding cushion of olive-green leaves, bearing masses of sweetly fragrant flowers for several weeks. This variety of Arabis Alpina ground cover seed produces a range of pink shades from mid spring to early summer. Wall Rock Cress ground covers are drought tolerant once established. They require good drainage, particularly in the winter months. These perennial ground cover plants should be trimmed lightly after blooming in order to maintain a bushy, compact habit. Rock Cress is an evergreen perennial. The Arabis seeds can be started indoors 6 - 8 weeks before the last frost or directly outdoors once temperatures are consistently warm.
