The only species of St John's-wort that has roughly hairy leaves and hairy stems and that does not grow in bogs. It is a medium to tall erect plant. The round section stem has two raised lines. The leaves have translucent dots but no marginal black glands. Flowers are pale yellow and sometimes red-veined borne in a lax many flowered panicle. The sepals are covered in tiny black spots.
