Coastal Mugwort is a resilient native perennial adapted to the rugged shorelines and open habitats of the West Coast. This species produces aromatic grey-green foliage and small clusters of yellowish flowers that attract pollinators throughout the summer. Like other mugworts, it has a long history of traditional use for its medicinal and ceremonial properties. It is drought-tolerant, deer-resistant, and thrives in tough coastal environments where other plants may struggle.

Best suited for Zones 3–9, this hardy perennial excels in dry, well-drained soils and full sun. It is ideal for coastal gardens, restoration sites, naturalised plantings, and wind-exposed areas.

History and Historical Uses
Used by Indigenous peoples of the Pacific Northwest, coastal mugwort was traditionally valued for smudging, cleansing, and spiritual protection. The leaves were also used in infusions and teas to relieve digestive issues and calm nerves. Like its European cousin, mugwort was seen as a powerful herb for dreaming and intuition.
