Known by many common names such as sea-oxeye daisy, sea marigold, beach carnation, seaside tansy and silver sea-oxeye, bushy seaside oxeye (Borrichia frutescens) is a perennial small to medium shrub with attractive daisy-like blooms. Each flower is comprised of 15-30 yellow ray florets surrounding many stiff yellow-orange disk florets with conspicuous black anthers. Flowers are approximately 1 inch in diameter. Leaves are oval to lanceolate and may be toothed toward their base, but otherwise have entire margins. They are grayish-green and pubescent, giving the foliage a silvery sheen. The fruit is a dark-colored cypsela and contains a single seed.
Bushy seaside oxeye occurs naturally in coastal strands, mangroves, beach dunes, salt marshes and tidal flats. It is very attractive to butterflies and other pollinators as it can bloom year-round. Its seeds provide food for birds and other small wildlife.
