In the garden
A member of the genus Arabis in the Brassicaceae, Arabis x suendermannii is grown principally as a low, spreading plant for rockeries and gravel gardens. It is valued for its mat-forming habit and spring display, and is commonly used at the front of borders or in containers on patios where a compact, evergreen cover is wanted. Place the plant in full sun and avoid heavy, waterlogged ground; it prefers well-drained conditions and will grow in chalk, clay, loam or sand and across acid to alkaline pH. An east-, south- or west-facing aspect suits it, and it stands up to both exposed and sheltered sites. The H6 rating means it is very hardy in UK gardens and will survive most outdoor winters without winter protection. Use Arabis x suendermannii in gravel and rock gardens, as a patio or container subject, or where a low evergreen layer is required in wildlife-friendly planting. Flowering runs from April to June, after which the persistent evergreen mats continue to define the planting area through summer, making it useful for holding edges and filling crevices between stones.
