Coastal Goldenbush
Isocoma menziesiiAlso known as Menzies' Goldenbush, Menzies' Coast Goldenbush
Coastal goldenbush forms rounded, evergreen shrub thickets along coastal bluffs, chaparral slopes, and sandy scrub across California and Baja California. During late summer and autumn, dense terminal clusters of bright yellow disc florets bloom above thick, resinous leaves with coarsely toothed margins. These hardy shrubs serve as critical late-season nectar sources for native bees and butterflies when few other coastal plants are in bloom.

Responsible observation
- Late Bloom Viewing: Look for vibrant yellow blossoms from mid-summer through autumn when other scrub plants dry out.

- Nectar Watching: Observe flowers closely during warm afternoons to spot native solitary bees and butterflies.
