Orophea thomsonii Plant Care

Orophea thomsonii (Orophea thomsonii) belongs to the Annonaceae family within the Orophea genus. Orophea thomsonii is native to Kerala and Tamil Nadu in India and endemic to the Western Ghats mountain range.

Orophea thomsonii displays a compact, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Orophea thomsonii produces small, fragrant flowers in shades of white, cream, or yellow.

Leaf size: approximately 4 inches.

Water a young or newly planted Orophea thomsonii 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.

Orophea thomsonii thrives in filtered sunlight, partial shade. Avoid placing Orophea thomsonii in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Orophea thomsonii tolerates temperatures of 65–80°F. Orophea thomsonii prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, rich loamy soil with added organic matter like compost. Good drainage is essential for Orophea thomsonii to prevent waterlogging, which leads to root rot and fungal issues.

Feed Orophea thomsonii 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 filtered sunlight, partial shade and well-draining, rich loamy soil with added organic matter like compost. Avoid low spots where water collects after rain.

Orophea thomsonii 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.

Orophea thomsonii 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 Orophea thomsonii 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.

Orophea thomsonii 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.

Orophea thomsonii can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to orophea creaghii plant care, which shares the same genus.

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

Orophea thomsonii grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Orophea thomsonii is native to Kerala and Tamil Nadu in India and endemic to the Western Ghats mountain range. In cooler regions, grow Orophea thomsonii as a houseplant or bring it indoors before the first frost.
