Silver Dollar Plant Plant Care

Silver Dollar Plant (Phyllolepidum cyclocarpum) belongs to the Brassicaceae family within the Phyllolepidum genus. Silver Dollar Plant is native to Italy, the Balkans and Turkey. Silver Dollar Plant is also known as Lunaria annua.

Silver Dollar Plant displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Silver Dollar Plant produces small clusters of white or yellow flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted Silver Dollar Plant 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.

Silver Dollar Plant thrives in full sun to partial shade.

Phyllolepidum cyclocarpum tolerates temperatures of 50–75°F. Silver Dollar Plant prefers humidity levels of 40–60%.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Silver Dollar Plant to prevent waterlogging, which leads to root rot and fungal issues.

Feed Silver Dollar Plant 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 loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Silver Dollar Plant is suited to USDA Zone 6a – 8b.

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.

Silver Dollar Plant 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 Silver Dollar Plant 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.

Silver Dollar Plant is hardy down to USDA zone 6a, 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.

Silver Dollar Plant can be propagated through seeds, division of offsets.

Silver Dollar Plant 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.
