Arabis x arendsii is a cheery pink flowering plant with rich green foliage. This is a great plant to add a vibrant splash of colour to pots, borders or a raised flowerbed. Theyre easy to cultivate. Like many of their human counterparts, Rockcress is a sun worshipper, so take care not to place her in too shady a spot. But it’s pretty hardy, and the ease of growing makes it a great choice for the beginner gardener. The blooms don’t spread, instead they form carpets of thick colour, flowering in late spring and early summer.
