Larch-leaved Celmisia Plant Care

Larch-leaved Celmisia (Celmisia laricifolia) belongs to the Asteraceae family within the Celmisia genus. Larch-leaved Celmisia is native to New Zealand.

Larch-leaved Celmisia displays a low rosette, clumping growth habit, reaching up to 1.5 ft tall with a spread of approximately 1.5 ft. Larch-leaved Celmisia produces daisy-like flowers in white, pink, or purple.

Leaf size: approximately 6 inches.

Water a young or newly planted Larch-leaved Celmisia every 7–14 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.

Larch-leaved Celmisia thrives in full sun to partial shade.

Celmisia laricifolia tolerates temperatures of 50–75°F. Larch-leaved Celmisia prefers humidity levels of 40–70%.

Well-draining sandy soil mix with added organic matter. Good drainage is essential for Larch-leaved Celmisia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Larch-leaved Celmisia 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 soil mix with added organic matter. Avoid low spots where water collects after rain.

Larch-leaved Celmisia is suited to USDA Zone 7a – 9b.

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.

Larch-leaved Celmisia can spread to about 2 ft (0.5 m) and reach about 2 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 Larch-leaved Celmisia 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.

Larch-leaved Celmisia is hardy down to USDA zone 7a, so once established it can stay outdoors through winter in that zone and warmer ones.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown shrubs need extra protection: roots in a pot freeze much more easily than roots in the ground.

Larch-leaved Celmisia can be propagated through seeds, division of clumps.

Larch-leaved Celmisia is susceptible to aphids, slugs, snails. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Larch-leaved Celmisia grows outdoors in USDA Zone 7a – 9b. It survives winters down to planting zone 7a. Larch-leaved Celmisia is native to New Zealand.
