Swamp Parrot Pea Plant Care

Swamp Parrot Pea (Dillwynia palustris) belongs to the Fabaceae family within the Dillwynia genus. Swamp Parrot Pea is native to the Snowy Mountains in New South Wales. Swamp Parrot Pea is also known as Parrot Pea.

Swamp Parrot Pea displays an upright, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Swamp Parrot Pea produces showy pea-like flowers in shades of yellow, orange, or red.

Leaf size: approximately 4 inches.

Water a young or newly planted Swamp Parrot Pea 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.

Swamp Parrot Pea thrives in full sun.

Dillwynia palustris tolerates temperatures of 50–80°F. Swamp Parrot Pea prefers humidity levels of 40–60%.

Well-draining sandy loam with added organic matter. Good drainage is essential for Swamp Parrot Pea to prevent waterlogging, which leads to root rot and fungal issues.

Feed Swamp Parrot Pea 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 and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Swamp Parrot Pea 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.

Swamp Parrot Pea 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 Swamp Parrot Pea 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.

Swamp Parrot Pea 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.

Swamp Parrot Pea can be propagated through seeds, cuttings. Similar propagation techniques also apply to prickly parrot pea plant care, which shares the same genus.
