Mitrasacme polymorpha Plant Care

Mitrasacme polymorpha (Mitrasacme polymorpha) belongs to the Loganiaceae family within the Mitrasacme genus. Mitrasacme polymorpha is native to eastern and southern Australia.

Mitrasacme polymorpha displays a low rosette, spreading growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Mitrasacme polymorpha produces small, tubular flowers in shades of white, pink, or purple.

Leaf size: approximately 2 inches.

Water a young or newly planted Mitrasacme polymorpha 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.

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

Mitrasacme polymorpha tolerates temperatures of 60–75°F. Mitrasacme polymorpha prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining sandy soil mix with added peat moss and perlite. Good drainage is essential for Mitrasacme polymorpha to prevent waterlogging, which leads to root rot and fungal issues.

Feed Mitrasacme polymorpha 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 sandy soil mix with added peat moss and perlite. Avoid low spots where water collects after rain.

Mitrasacme polymorpha 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.

Mitrasacme polymorpha can spread to about 1 ft (0.3 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Mitrasacme polymorpha 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.

Mitrasacme polymorpha 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.

Mitrasacme polymorpha can be propagated through seeds, division of clumps.

Mitrasacme polymorpha 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.

Mitrasacme polymorpha grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Mitrasacme polymorpha is native to eastern and southern Australia. In cooler regions, grow Mitrasacme polymorpha as a houseplant or bring it indoors before the first frost.
