Senecio minimus

Coastal burnweed

Family: Asteraceae · Type: perennial · Not Native

Coastal burnweed is a naturalized perennial herb found in northern coastal California, western coastal California, and western Central Western regions in disturbed coastal sites at elevations below 200 meters. Flowering from June to September, this plant produces light yellow-green flower heads in rounded to flat-topped clusters with inconspicuous outer phyllaries. Growing 5 to 20 decimeters tall with stems branched distally and sparsely tomentose, it develops from a taproot with branched lateral roots. Its leaves are narrowly lanceolate, 4 to 20 centimeters long and 1 to 4 centimeters wide, with sharply and evenly fine-toothed margins that taper to short, somewhat clasping petioles. The plant produces small fruits 1.5 to 2.5 millimeters long, typically hairy in the grooves between ribs.
