Arenaria
Sandwort

CAROPHYLLACEAE
Herbaceous Perennials and Annuals

Arenaria. purpurascens

Arenaria. balearica

Most of the Sandworts are low-growing or spreading perennials, some of which are evergreen, although there are a few are annuals within the genus. All have narrow, greyish green leaves, that can form loose mats or dense cushions, covered in late spring and early summer with a profusion of mostly white flowers. Arenaria thrive in dry conditions and are suitable for the rock garden and growing in the crevices found in dry stone walling. Grown in the gaps between the paving slabs of a patio they can be used to soften the edges and transform a bare area.
