Dianthus arenarius seeds

The Sand perennial Carnation, in Latin Dianthus arenarius, is a valuable botanical species for dry, sandy or rocky soils, in cold climates. Originating from coastal regions of Northern Europe, this plant stands out for its cold resistance and low water requirements. Its white flowers display finely cut petals and emit a delicate fragrance. This summer flowering will bring a touch of lightness and charm to rockeries and border edges.

Dianthus arenarius belongs to the Caryophyllaceae family, like all carnations. This species is native to the Baltic Sea coasts, especially Sweden and the Baltic countries. In the wild, the plant thrives on sandy, poor, and well-drained soils. This perennial forms compact clumps of 20 to 30 cm in height. Its leaves are linear, dark green, and quite thin, resembling grass. They persist through winter. Flowering occurs from June to August, in the form of white, 2 to 3 cm diameter flowers. The petals are deeply cut along the edges, giving the flower a distinct finely toothed appearance. The flowers release a gentle fragrance, especially in the evening. They are carried by thin but sturdy stems.

To accompany the Sand perennial Carnation, choose small hardy plants suited for sandy soils such as Armeria maritima, Sea Thrift, which forms small tufts and produces pink, red, white, or purple flowers or Silene maritima 'Weisskehlchen', another light coastal plant with white bell-shaped flowers. Also consider Eryngium maritimum (Sea Holly), with its architectural, bluish foliage and round flowers. Sedum acre 'Yellow Queen', forming a green carpet and yellow flowers, will complement this plant palette.
