Viscaria vulgaris, the sticky catchfly[3] or clammy campion,[4] is a flowering plant in the family Caryophyllaceae.

The flowers, which are 20 mm across and bright rosy-pink, appear in long whorled spikes from May to August.

[5][6] In Central Europe, Lychnis viscaria can be found in a variety of habitats, such as dry meadows, lush grasslands, stony slopes, rocky outcrops of hilly terrain, and open or sparse canopied forests.

In British horticultural literature it is often referred to by its synonym Lychnis viscaria.

[9] The cultivar 'Splendens Plena', a double-flowered form, has won the Royal Horticultural Society's Award of Garden Merit.
