Sea Oxeye Daisy
Borrichia frutescense
This meadow of Silver Sea Oxeye Daisy is growing next to a saltmarsh just west of the dune in Stuart, Florida. Those are mangroves in the background. The soil is moist and salty with other salt tolerant species like Cakile, Salt meadow Cordgrass and Sea Purslane growing with it.
In the drier soils next to this are Dune Sunflower, Beach Verbena, Goats Foot and Seaside Morning glory. When using this plant, keep in mind that it spreads aggressively though underground roots and may need a border to keep it in place.
