Exiled pachycladon Plant Care

Exiled pachycladon (Pachycladon exile) belongs to the Brassicaceae family within the Pachycladon genus. Exiled pachycladon is native to the South Island of New Zealand. Exiled pachycladon is also known as New Zealand rock daisy.

Exiled pachycladon displays a low rosette, spreading growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Exiled pachycladon produces small white or yellow flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Exiled pachycladon 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.

Exiled pachycladon thrives in full sun to partial shade.

Pachycladon exile tolerates temperatures of 50–75°F. Exiled pachycladon prefers humidity levels of 40–60%.

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

Feed Exiled pachycladon 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.

Exiled pachycladon is suited to USDA Zone 8a – 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.

Exiled pachycladon 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 Exiled pachycladon 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.

Exiled pachycladon is hardy down to USDA zone 8a, 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.

Exiled pachycladon can be propagated through seeds, division.

Exiled pachycladon is susceptible to aphids, cabbage worms, flea beetles. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.
