Platylobium infecundum Plant Care

Platylobium infecundum (Platylobium infecundum) belongs to the Fabaceae family within the Platylobium genus. Platylobium infecundum is native to Victoria, Australia.

Platylobium infecundum displays an upright, bushy shrub growth habit, reaching up to 4 ft tall with a spread of approximately 3 ft. Platylobium infecundum produces showy pea-like flowers in various colors.

Leaf size: approximately 4 inches.

Water a young or newly planted Platylobium infecundum 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.

Platylobium infecundum thrives in full sun to partial shade.

Platylobium infecundum tolerates temperatures of 50–85°F. Platylobium infecundum prefers humidity levels of 40–70%.

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

Feed Platylobium infecundum 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

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

Platylobium infecundum 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.

Platylobium infecundum can spread to about 3 ft (0.9 m) and reach about 4 ft (1 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Platylobium infecundum 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.

Platylobium infecundum 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.

Platylobium infecundum can be propagated through seeds, cuttings. Similar propagation techniques also apply to native pea plant care, which shares the same genus.

Platylobium infecundum is susceptible to aphids, leafhoppers, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Platylobium infecundum grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Platylobium infecundum is native to Victoria, Australia. In cooler regions, grow Platylobium infecundum as a houseplant or bring it indoors before the first frost.
