Seaside Bird's Beak Plant Care

Seaside Bird's Beak (Cordylanthus maritimus) belongs to the Orobanchaceae family within the Cordylanthus genus. Seaside Bird's Beak is native to western North America. Seaside Bird's Beak is also known as Salt Marsh Bird's Beak.

Seaside Bird's Beak displays an upright, branching shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Seaside Bird's Beak produces tubular flowers in shades of red, orange, or yellow.

Leaf size: approximately 4 inches.

Water a young or newly planted Seaside Bird's Beak every 7–10 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.

Seaside Bird's Beak thrives in full sun to partial shade.

Cordylanthus maritimus tolerates temperatures of 60–80°F. Seaside Bird's Beak prefers humidity levels of 40–60%.

Well-draining sandy soil with added organic matter for nutrients. Good drainage is essential for Seaside Bird's Beak to prevent waterlogging, which leads to root rot and fungal issues.

Feed Seaside Bird's Beak 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 for nutrients. Avoid low spots where water collects after rain.

Seaside Bird's Beak is suited to USDA Zone 13a.

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.

Seaside Bird's Beak can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Seaside Bird's Beak 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.

Seaside Bird's Beak is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Seaside Bird's Beak can be propagated through seeds, division of offsets. Similar propagation techniques also apply to capitate bird's beak plant care, which shares the same genus.
