Aethionema grandiflorum
Persian Stonecress
Zone 5 to Zone 9
Plant Shapes: Cushion Subshrub

Native to the Middle East, this is a low shrubby perennial that forms a beautiful cushioned mound of soft blue-green needle-shaped leaves. Small clusters of light rose-pink blooms are produced over many weeks in late spring and early summer. Grows best in poor, dry alkaline soil but needs excellent drainage. Dislikes winter wet. Prune lightly after blooming to maintain a bushy habit. Although not a long-lived perennial, this will self-seed where happy. A terrific choice for sunny rock gardens and walls or alpine troughs. May need protection from browsing deer. May prove to be hardy in colder regions if snowcover is reliable.
