Heartleaf Dalibarda Plant Care

Heartleaf Dalibarda (Dalibarda cordata) belongs to the Rosaceae family within the Dalibarda genus. Heartleaf Dalibarda is native to eastern and central Canada and to the northeastern and north-central United States.

Heartleaf Dalibarda displays a low rosette, spreading groundcover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1.5 ft. Heartleaf Dalibarda produces small white or pink flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Heartleaf Dalibarda 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.

Heartleaf Dalibarda thrives in partial to full shade. The optimal light range is 100–500 lux. Avoid placing Heartleaf Dalibarda in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Dalibarda cordata tolerates temperatures of 50–75°F. Heartleaf Dalibarda prefers humidity levels of 40–60%.

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

Feed Heartleaf Dalibarda 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 partial to full shade and moist, well-draining soil with high organic content. Avoid low spots where water collects after rain.

Heartleaf Dalibarda 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.

Heartleaf Dalibarda 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 Heartleaf Dalibarda 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.

Heartleaf Dalibarda 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.

Heartleaf Dalibarda can be propagated through seeds, division of rhizomes.

Heartleaf Dalibarda grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Heartleaf Dalibarda is native to eastern and central Canada and to the northeastern and north-central United States. In cooler regions, grow Heartleaf Dalibarda as a houseplant or bring it indoors before the first frost.
