Calomeria gracillima Plant Care

Calomeria gracillima (Calomeria gracillima) belongs to the Asteraceae family within the Calomeria genus. Calomeria gracillima is native to Western Australia, and regarded Thiseltonia dyeri as a synonym, while Plants of the World Online accepted Thiseltonia dyeri as a separate species.

Calomeria gracillima displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1.5 ft. Calomeria gracillima produces small daisy-like flowers in shades of white, pink, or purple.

Leaf size: approximately 2 inches.

Water a young or newly planted Calomeria gracillima 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.

Calomeria gracillima thrives in full sun to partial shade.

Calomeria gracillima tolerates temperatures of 50–80°F. Calomeria gracillima prefers humidity levels of 40–70%.

Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for Calomeria gracillima to prevent waterlogging, which leads to root rot and fungal issues.

Feed Calomeria gracillima 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with full sun to partial shade and well-draining sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Calomeria gracillima is suited to USDA Zone 12a.

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.

Calomeria gracillima can spread to about 2 ft (0.5 m) and reach about 1 ft (0 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 Calomeria gracillima 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.

Calomeria gracillima 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.

Calomeria gracillima can be propagated through seeds, division of clumps. Similar propagation techniques also apply to amaranth calomeria plant care, which shares the same genus.

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

Calomeria gracillima grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Calomeria gracillima is native to Western Australia, and regarded Thiseltonia dyeri as a synonym, while Plants of the World Online accepted Thiseltonia dyeri as a separate species. In cooler regions, grow Calomeria gracillima as a houseplant or bring it indoors before the first frost.
