Circaea cordata Plant Care

Circaea cordata (Circaea cordata) belongs to the Onagraceae family within the Circaea genus.

Circaea cordata displays a low spreading groundcover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Circaea cordata produces small white or pink flowers in racemes.

Leaf size: approximately 2 inches.

Water a young or newly planted Circaea cordata every 3–5 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.

Circaea cordata thrives in part shade to full shade. The optimal light range is 50–500 lux. Avoid placing Circaea cordata in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Circaea cordata tolerates temperatures of 50–75°F. Circaea cordata prefers humidity levels of 40–70%.

Moist, rich, well-draining soil with high organic content. Good drainage is essential for Circaea cordata to prevent waterlogging, which leads to root rot and fungal issues.

Feed Circaea cordata 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 part shade to full shade and moist, rich, well-draining soil with high organic content. Avoid low spots where water collects after rain.

Circaea cordata 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.

Circaea cordata 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 Circaea cordata 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.

Circaea cordata 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.

Circaea cordata can be propagated through division, seeds. Similar propagation techniques also apply to alpine enchanter's nightshade plant care, which shares the same genus.

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

Circaea cordata grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. In cooler regions, grow Circaea cordata as a houseplant or bring it indoors before the first frost.
