About
Sea oxeye daisy (Borrichia frutescens) is a salt-spray tough perennial shrublet of coastal dunes, mangrove edges, and brackish flats around the Gulf and Atlantic coasts of the Americas. Bright yellow radiate flowers cap succulent, often gray-green foliage. It is a backbone plant for dune restoration and coastal polycultures where inland daisies would desiccate in a week. Full sun; anything less invites leggy weak growth. Drought tolerant in maritime exposure once established; occasional salt wetting is normal. Pure sand to shell; intolerant of heavy shade and stagnant freshwater pots. Semi-hardwood cuttings in warm seasons with fast-draining mix. Seeds when available; sow in sandy mix with salt regime matching destination. Trim storm damage after calm weather to reshape mounds. Not a primary food plant; ornamental and ecological value lead. Deadhead only if invasive seeding is a documented local issue—otherwise leave seed heads for birds. Mulch with shell sand, not bark, in authentic coastal designs.
Permaculture Functions
- Ornamental: Borrichia frutescens rubbery shrubs carry chrome-yellow radiate heads above gray succulent leaves -- reads graphic against shell hash and turquoise water without irrigation guilt.
- Pollinator: Coastal halictids and syrphids work short-ray flowers -- when steady trade wind keeps inland daisy species folded.
- Erosion Control: Woody crowns resprout after salt splash so foredune mats hold sand -- where annual colonizers wash away each spring tide series.
- Wildlife Attractor: Seed heads feed small passerines -- while stiff stems anchor spider silk that catches insect drift above high tide wrack.
