Amarolea americana Plant Care

Amarolea americana (Amarolea americana) belongs to the Oleaceae family within the Amarolea genus. Amarolea americana is native to southeastern North America, in the United States from Virginia to Texas, and in Mexico from Nuevo León south to Oaxaca and Veracruz.

Amarolea americana displays a compact, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Amarolea americana produces small fragrant white flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Amarolea americana 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.

Amarolea americana thrives in full sun to partial shade.

Amarolea americana tolerates temperatures of 60–80°F. Amarolea americana prefers humidity levels of 40–70%.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Amarolea americana to prevent waterlogging, which leads to root rot and fungal issues.

Feed Amarolea americana 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 loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Amarolea americana is suited to USDA Zone 13a.

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.

Amarolea americana 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 Amarolea americana 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.

Amarolea americana 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.

Amarolea americana can be propagated through softwood cuttings, layering.

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

Amarolea americana grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Amarolea americana is native to southeastern North America, in the United States from Virginia to Texas, and in Mexico from Nuevo León south to Oaxaca and Veracruz. In cooler regions, grow Amarolea americana as a houseplant or bring it indoors before the first frost.
