Arabis alpina subsp. caucasica Snowcap

The 'Arabis caucasica 'Snowcap' is a new variety of rock cress, particularly floriferous, with a very compact growth that disappears in spring under many small pure white flowers, forming a carpet of snow in flower beds. This perennial plant forms a very effective ground cover tapestry to fight against weeds. It is particularly decorative with its tiny green foliage that turns decorative grey throughout the year. Easy to grow in well-drained soil, it is perfect for covering walls, climbing slopes, covering the base of hedges, dressing the base of plants in pots, or bordering gravel paths.

The Arabis alpina subsp. caucasica belongs to the Brassicaceae family. This very hardy plant is native to temperate regions of the Northern Hemisphere. 'Snowcap', sometimes called Arabis caucasica 'Scneehaube', was recently selected in Germany for its dense, low habit and excellent floribundity. It is an evergreen and spreading perennial that spreads by rhizomes, and its growth is relatively slow. It forms a dense ground cover of 10-15 cm (4-6in) in height, with a minimum spread of 35 cm (14in), theoretically unlimited. The flowering takes place from April to June, depending on the climate. Its produces many small flowers, 1 cm (1in) in diameter, slightly fragrant, are gathered in generous clusters. They bloom above the green to grey-green foliage with a plush appearance. The leaves form compact rosettes; they are oval, serrated and measure 2 cm (1in) long.

Perfect rockery plants, one of the most robust rock cresses, also make excellent ground covers along the edges of flower beds, in paving, as a topping for walls, on slopes, etc. Arabis caucasica 'Snowcap' is a beautiful plant that can cover a large area in just a few years and help prevent weed growth. It's great for covering the base of shrubs or hedges, even in partial shade. However, it's not recommended to plant it in a well-maintained rockery as it may harm other delicate plants. This plant is very easy to grow, much like ivy, and will flower every year alongside tulips and other spring bulbs. It has a long lifespan and requires little maintenance.
