Sea Oxeye Daisy Plant Care

Sea Oxeye Daisy (Borrichia frutescens) belongs to the Asteraceae family within the Borrichia genus. Sea Oxeye Daisy is native to the United States and Mexico. Sea Oxeye Daisy is also known as False Goldenrod, Saltmarsh Elder, Borrichia frutescens.

Sea Oxeye Daisy displays a low spreading groundcover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1.5 ft. Sea Oxeye Daisy produces small yellow daisy-like flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted Sea Oxeye Daisy every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Sea Oxeye Daisy thrives in full sun to partial shade.

Borrichia frutescens tolerates temperatures of 50–85°F. Sea Oxeye Daisy prefers humidity levels of 40–70%.

Well-draining sandy soil with added organic matter. Good drainage is essential for Sea Oxeye Daisy to prevent waterlogging, which leads to root rot and fungal issues.

Feed Sea Oxeye Daisy every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Choose a spot with full sun to partial shade and well-draining sandy soil with added organic matter. Avoid low spots where water collects after rain.

Sea Oxeye Daisy is suited to USDA Zone 12a.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Sea Oxeye Daisy can spread to about 2 ft (0.5 m) and reach about 1 ft (0 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Sea Oxeye Daisy while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.

Sea Oxeye Daisy is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Sea Oxeye Daisy can be propagated through seeds, division. Similar propagation techniques also apply to tree seaside sunflower plant care, which shares the same genus.
