African Palo Verde Plant Care

African Palo Verde (Parkinsonia africana) belongs to the Fabaceae family within the Parkinsonia genus. African Palo Verde is native to southern Angola, Botswana, and Namibia, and the Cape Provinces and Northern Provinces of South Africa. African Palo Verde is also known as Green Thorn, Parkinsonia africana.

African Palo Verde displays a spreading, thorny tree growth habit, reaching up to 20 ft tall with a spread of approximately 20 ft. African Palo Verde produces bright yellow, fragrant flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted African Palo Verde every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

African Palo Verde thrives in full sun.

Parkinsonia africana tolerates temperatures of 50–100°F. African Palo Verde prefers humidity levels of 10–60%.

Well-draining sandy soil with low fertility. Good drainage is essential for African Palo Verde to prevent waterlogging, which leads to root rot and fungal issues.

Feed African Palo Verde every 8 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees 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 soil with low fertility. Avoid low spots where water collects after rain.

African Palo Verde is suited to USDA Zone 12a.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

African Palo Verde can spread to about 20 ft (6.1 m) and reach about 20 ft (6 m) tall. Space plants about 20 ft (6.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune African Palo Verde 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 tree in one year.

African Palo Verde 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.

African Palo Verde can be propagated through seeds. Similar propagation techniques also apply to palo verde plant care, which shares the same genus.

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

African Palo Verde grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. African Palo Verde is native to southern Angola, Botswana, and Namibia, and the Cape Provinces and Northern Provinces of South Africa. In cooler regions, grow African Palo Verde as a houseplant or bring it indoors before the first frost.
