Arabis Alpina (Rock Cress, or Snow in Summer).
Pure white hardy perennial, which is valuable for spring bedding. Not particular to soil, and easily raised from seed sown from March to June, placed under a frame, and transplanted in the autumn, or it may be propagated by slips, but more surely by rootlets taken after the plants have done flowering. Plant 3 in. apart. Height, 6 in.
