COMMON NAME: Coastal Glehnia
Plant Profile
Glehnia littoralis, commonly known as Coastal Glehnia, is a perennial in the parsley family. Coastal glehnia keeps low, clump-forming habit with broad, glossy leaves and small, white flowers in flat-topped clusters, and the whole plant carries the fine, neat look of the seaside garden. It is a plant of open, sunny, deep, light, sandy, well-drained ground. Bees find the flowers quickly, and that pollinator traffic is a garden benefit in its own right. Add these qualities together and you have a species well worth a place in the garden.
Science & Biotechnology
Bei sha shen is the root of a coastal sand-dune plant, listed in the Chinese Pharmacopoeia as a yin-nourishing drug for dry coughs and parched throats. Its chemistry is coumarin-rich — imperatorin, isoimperatorin and psoralen derivatives — with documented anti-inflammatory and antispasmodic activity in laboratory work, alongside polysaccharides studied for immune effects. The wild plant, once common on the dunes of China’s northern coasts, has become scarce from collection and development, so cultivated seed stock genuinely matters for this species.
Like other members of the parsley family, Glehnia littoralis draws steady attention from botanists and plant breeders, who value the genus both as a subject of research and as a source of garden-worthy material. Little about its garden performance is mysterious; it has been grown and observed for a very long time.
