Artemisia pycnocephala
Artemisia pycnocephala, commonly known as Sandhill Sagewort or Beach Sagewort, is a drought-tolerant perennial shrub native to the coastal dunes and bluffs of western North America. It features silvery-gray, aromatic foliage and inconspicuous yellowish flowers. Its dense growth habit makes it an excellent choice for erosion control and stabilizing sandy soils. It is highly adaptable to harsh coastal conditions, including strong winds and salt spray.
