Flowers 3–6 mm in diameter, in loose dichasia , on erect pedicels 5–20 mm long, with a five-membered perianth. Calyx is wide - bell-shaped or funnel-shaped, shallowly divided, up to 3 mm long, glabrous, white, with green veins. Petals 4.5-6 mm long, pink, with darker veins, or white, with a pale green fingernail, narrow wedge-shaped, the margin of denture is dentate. Stamens in number 10.

The fruit is a narrow egg- shaped box 3.5-4.5 × 2-2.5 mm; when ripening, it opens with four wings. Seeds are small - up to 0.5 mm long, numerous, black, triangular-pear-shaped in shape, small-tuberous.

The species is widespread in Eurasia, in Russia - throughout the European part, in Siberia and the Far East. It is found on sand, along roads and wastelands, as a rule, without stopping for a long time, being crowded out by other species.

Introduced in the north-eastern part of North America, where it naturalized.

In recent years, attempts have been made to introduce varieties with strongly branched stems with many flowers, with double and larger flowers, with a brighter color of the flowers.

Sometimes Psammophiliella stepposa (Klokov) Ikonn stands out as an independent species or variety . - steppe sand-lover, characterized by white flowers and narrow-linear leaves no more than 1 mm wide.
