It is also known soil. The plant develops a Plant Materials Center (PMC) as beach groundsel and seaside (Wright, 2005). ragwort. taproot which drills deep into the earth for water. This native herb is a Selected Growing on gravelly and sandy Class Release by the PMC. This seashores, beach fleabane Senecio pseudoarnica has means it has been grown and withstands the salt spray from the fleshy stems and many basal harvested at the PMC and ocean. olive-green leaves.
