White Bean-Caper Plant Care

White Bean-Caper (Zygophyllum album) belongs to the Zygophyllaceae family within the Zygophyllum genus. White Bean-Caper is native to arid regions of Africa and the Arabian Peninsula. White Bean-Caper is also known as White Caltrop.

White Bean-Caper displays a low spreading shrub growth habit, reaching up to 1.5 ft tall with a spread of approximately 3 ft. White Bean-Caper produces small, star-shaped flowers in shades of white, yellow, or pink.

Leaf size: approximately 1.5 inches.

Water a young or newly planted White Bean-Caper 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.

White Bean-Caper thrives in full sun to partial shade.

Zygophyllum album tolerates temperatures of 50–90°F. White Bean-Caper prefers humidity levels of 30–60%.

Sandy, well-draining soil with low to moderate fertility, such as a mix of sand, loam, and gravel. Good drainage is essential for White Bean-Caper to prevent waterlogging, which leads to root rot and fungal issues.

Feed White Bean-Caper 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 sandy, well-draining soil with low to moderate fertility, such as a mix of sand, loam, and gravel. Avoid low spots where water collects after rain.

White Bean-Caper is suited to USDA Zone 9b – 11b.

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.

White Bean-Caper can spread to about 3 ft (0.9 m) and reach about 2 ft (0 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 White Bean-Caper 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.

White Bean-Caper is frost-tender (hardy to USDA zone 9). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

White Bean-Caper can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to cretan bean-caper plant care, which shares the same genus.

White Bean-Caper is susceptible to aphids, whiteflies, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

White Bean-Caper grows outdoors in USDA Zone 9b – 11b. It survives winters down to planting zone 9b. White Bean-Caper is native to arid regions of Africa and the Arabian Peninsula. In cooler regions, grow White Bean-Caper as a houseplant or bring it indoors before the first frost.
