Red campion

Native · flowers May–Sep · woodland edges, hedge banks and verges

Silene dioica — Caryophyllaceae

Red campion is the pink-red flower that follows the bluebells on hedge banks and woodland edges from May, with five deeply notched petals. Male and female flowers are on different plants. It hybridises with white campion where the two meet, producing pinkish-white plants. It is also an ancient woodland indicator.

How to spot them

  • ▸Bright pink-red flowers with five petals, each notched to about halfway, rising from a tubular, purple-brown calyx
  • ▸Male flowers have a narrower calyx; female flowers have a fatter, more inflated calyx
  • ▸Hairy stems and hairy, opposite, pointed-oval leaves
  • ▸Male and female flowers grow on separate plants (dioecious)
  • ▸White campion (Silene latifolia) is the look-alike: white flowers, sticky-hairy stems, more open and often scented at night. Where they grow together the two hybridise, giving pinky-white flowers
