Sea Buckthorn
Hippophae rhamnoides
fruitSea Buckthorn is a hardy, nitrogen-fixing shrub producing bright orange berries rich in vitamins, omega oils, and antioxidants. This salt-tolerant plant thrives in coastal and exposed locations, adapting to poor, sandy soils where few plants survive. Male and female plants are required for fruit production; berries cling to branches through winter.
