Trifolium wormskioldii

Trifolium wormskioldii, commonly known as the springbank clover or Wormskiold's clover, is a species of flowering plant in the legume family, Fabaceae. It is native to the western coastal regions of North America, from Alaska to California, where it thrives in moist, sandy soils, often in the vicinity of saltwater. This perennial herb is notable for its adaptability to both freshwater and saline environments, making it a unique member of the Trifolium genus.

Description

Trifolium wormskioldii is a perennial plant that can grow up to 60 cm in height, with a robust, creeping rhizome. Its stems are erect or ascending, often rooting at the nodes. The leaves are trifoliate, with each leaflet ranging from oval to oblong, and are often marked with a white chevron.
