Showy Rattlepod Plant Care

Showy Rattlepod (Crotalaria spectabilis) belongs to the Fabaceae family within the Crotalaria genus. Showy Rattlepod is native to the Indian Subcontinent, southern China, and Southeast Asia. Showy Rattlepod is also known as Green Summer-Pea, Rattlebox.

Showy Rattlepod displays an upright, branching shrub growth habit, reaching up to 4 ft tall with a spread of approximately 3 ft. Showy Rattlepod produces showy yellow, orange, or red pea-like flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Showy Rattlepod 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.

Showy Rattlepod thrives in full sun to partial shade.

Crotalaria spectabilis tolerates temperatures of 65–85°F. Showy Rattlepod prefers humidity levels of 40–60%.

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

Feed Showy Rattlepod 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 loam with added organic matter. Avoid low spots where water collects after rain.

Showy Rattlepod is suited to USDA Zone 13b.

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.

Showy Rattlepod 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 Showy Rattlepod 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.

Showy Rattlepod 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.

Showy Rattlepod can be propagated through seeds. Similar propagation techniques also apply to rattlepod plant care, which shares the same genus.

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

Showy Rattlepod grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Showy Rattlepod is native to the Indian Subcontinent, southern China, and Southeast Asia. In cooler regions, grow Showy Rattlepod as a houseplant or bring it indoors before the first frost.
