The Coastal Scouler’s Catchfly, Silene scouleri spp. Grandis, is a hairy perennial in the Pink Family of flowering plants. It is named after the sticky hairs on its leaves that can trap small insects which try to steal nectar without pollinating the flowers. It is a Red-listed, Endangered species. This species is distinctive for its greenish-white to purplish striped flowers clustered in a narrow spike-like arrangement. The slender pale green leaves are hairy and grow in a rosette of basal leaves that are up to 20 cm long with paired opposite leaves gradually reducing in size up the stem. The whole plant can be 15-80 cm tall and grows erect. It is most likely insect pollinated. The fruit is a dark egg-shaped capsule containing numerous small greyish brown pimply seeds which ripen in September or October and drop from the plants in November.
