Barnhartia floribunda Plant Care

Barnhartia floribunda (Barnhartia floribunda) belongs to the Polygalaceae family within the Barnhartia genus. Barnhartia floribunda is native to Venezuela, the Guianas, and Northern Brazil.

Barnhartia floribunda displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Barnhartia floribunda produces small, delicate purple flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Barnhartia floribunda 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.

Barnhartia floribunda thrives in partial shade to dappled sunlight. Avoid placing Barnhartia floribunda in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Barnhartia floribunda tolerates temperatures of 60–75°F. Barnhartia floribunda prefers humidity levels of 40–60%.

Well-draining loamy soil with added organic matter for moisture retention. Good drainage is essential for Barnhartia floribunda to prevent waterlogging, which leads to root rot and fungal issues.

Feed Barnhartia floribunda 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 shade to dappled sunlight and well-draining loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Barnhartia floribunda is suited to USDA Zone 13a.

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.

Barnhartia floribunda 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 Barnhartia floribunda 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.

Barnhartia floribunda is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Barnhartia floribunda can be propagated through seeds, division of rhizomes.
