Silene viscaria, the sticky catchfly[2] or clammy campion,[3] is a flowering plant in the family Caryophyllaceae.

It is an upright perennial, growing to 60 cm in height. It gets its English name from the stickiness of its stem. It grows on cliffs and in rocky places. It has a purple flower.

Stace[4] and Fitter[5] describe this plant as having the following characteristics:

  • Erect perennial to 60 cm (24 in) high
  • Not hairy or only slightly hairy
  • Sticky just below each leaf junction
  • Leaves lanceolate
  • Flowers 20 mm (0.79 in) across; bright rosy red; petals notched; apparently whorled in long spikes; May–August

Lychnis viscaria is said to increase the disease resistance of surrounding plants. Extract from L. viscaria contains a relatively high amount of brassinosteroids, which have a proven positive effect on the growth of other plants. In Germany the extract is allowed for use as a "plant strengthening substance".
