Silene douglasii is a species of flowering plant in the pink family known by the common name Douglas's catchfly.[1]

It is native to western North America from British Columbia to California to Wyoming, where it grows in several habitat types, including forests, woodlands, and coastal scrub.[1]

Description[edit]

Silene douglasii is a tufted perennial herb growing from a branching caudex and taproot, its stems decumbent to erect and up to 70 centimeters long. The stem is coated in curly or feltlike gray-white hairs. The lance-shaped leaves are up to 6 centimeters long on the lower stem and are smaller farther up.

Each flower is encapsulated in a cylindrical inflated calyx of sepals lined with ten green or purple-red veins. It is open at the tip, revealing five white, pink or purplish petals, each with two wide lobes at the tip.

Varieties[edit]

There are three varieties of this species.

  • Silene douglasii var. douglasii [2][3]
  • Silene douglasii var. oraria — Seabluff catchfly, rare and endemic to the Oregon coastline.[4]
  • Silene douglasii var. rupinae [5]
