The silver sea oxeye is an upright to roundish shrub that grows 2 to 4 feet in height near brackish water (Fig. 1). The leaves of this plant are fleshy, leathery, and gray-green in color. The daisy-like flowers have yellow disks that are larger than its yellow rays; the yellow color of the flower is subtle. Flowers are borne mostly in the spring but some can be seen into the summer. This plant has fruits that are small, sharp, needle-like achenes.

Use and Management

Silver sea oxeye is a totally salt-resistant plant that performs well as a low hedge or ground cover near the ocean. This plant takes shearing quite well and is often used in a garden as an edging along a sidewalk.

The silver sea oxeye tolerates brackish conditions and varied soils. It requires a position in the landscape that receives full sun and can survive the extremely dry conditions of winter and early spring. It should adapt to conditions in many landscapes, provided they are not irrigated regularly.

This plant may be propagated from seeds and cuttings.
