Also known as Rock Cress, this dainty alpine plant produces hundreds of tiny cream flowers in spring which have a delicate sweet fragrance. Arabis caucasica 'Pixie Cream' has a spreading habit and forms tidy cushions of grey-green foliage which are perfect for groundcover, rock gardens, wall crevices and patio containers. Drought tolerant and easy to grow, Arabis are the ultimate low-maintenance perennial. Height: 10cm (4). Spread: 25cm (10).
