Notonia amaniensis Plant Care

Notonia amaniensis (Kleinia amaniensis) belongs to the Asteraceae family within the Kleinia genus. Notonia amaniensis is also known as Senecio amaniensis.

Notonia amaniensis displays an upright, branching shrub growth habit, reaching up to 2 ft tall with a spread of approximately 1.5 ft. Notonia amaniensis produces small, daisy-like flowers in shades of white, pink, or purple.

Leaf size: approximately 3 inches.

Water a young or newly planted Notonia amaniensis every 10–14 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.

Notonia amaniensis thrives in bright indirect light. Avoid placing Notonia amaniensis in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Kleinia amaniensis tolerates temperatures of 60–80°F. Notonia amaniensis prefers humidity levels of 40–60%.

Well-draining succulent mix with added perlite for extra drainage. Good drainage is essential for Notonia amaniensis to prevent waterlogging, which leads to root rot and fungal issues.

Feed Notonia amaniensis 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 bright indirect light and well-draining succulent mix with added perlite for extra drainage. Avoid low spots where water collects after rain.

Notonia amaniensis 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.

Notonia amaniensis can spread to about 2 ft (0.5 m) and reach about 2 ft (1 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Notonia amaniensis 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.

Notonia amaniensis 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.

Notonia amaniensis can be propagated through stem cuttings, division. Similar propagation techniques also apply to coral-jewels plant care, which shares the same genus.

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

Notonia amaniensis grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. In cooler regions, grow Notonia amaniensis as a houseplant or bring it indoors before the first frost.
