Caucasian cudweed Plant Care

Caucasian cudweed (Omalotheca caucasica) belongs to the Asteraceae family within the Omalotheca genus. Caucasian cudweed is native to Turkey and the Caucasus. Caucasian cudweed is also known as Caucasian cottonrose.

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

Leaf size: approximately 2 inches.

Water a young or newly planted Caucasian cudweed 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.

Caucasian cudweed thrives in full sun to partial shade.

Omalotheca caucasica tolerates temperatures of 50–75°F. Caucasian cudweed prefers humidity levels of 40–60%.

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

Feed Caucasian cudweed 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 sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Caucasian cudweed 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.

Caucasian cudweed 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 Caucasian cudweed 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.

Caucasian cudweed 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.

Caucasian cudweed can be propagated through seeds, division of clumps. Similar propagation techniques also apply to gamochaeta norvegica plant care, which shares the same genus.

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

Caucasian cudweed grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Caucasian cudweed is native to Turkey and the Caucasus. In cooler regions, grow Caucasian cudweed as a houseplant or bring it indoors before the first frost.
