Integrifolia Slipperwort Plant Care

Integrifolia Slipperwort (Calceolaria integrifolia) belongs to the Calceolariaceae family within the Calceolaria genus. Integrifolia Slipperwort is native to Argentina and Chile. Integrifolia Slipperwort is also known as Shrubby Calceolaria.

Integrifolia Slipperwort displays a compact, mounding habit growth habit, reaching up to 0.5 ft tall with a spread of approximately 0.5 ft. Integrifolia Slipperwort produces unique pouch-shaped flowers in various colors.

Leaf size: approximately 2 inches.

Water a young or newly planted Integrifolia Slipperwort 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.

Integrifolia Slipperwort thrives in bright indirect light. Avoid placing Integrifolia Slipperwort in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Calceolaria integrifolia tolerates temperatures of 60–75°F. Integrifolia Slipperwort prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, fertile soil with added organic matter. Good drainage is essential for Integrifolia Slipperwort to prevent waterlogging, which leads to root rot and fungal issues.

Feed Integrifolia Slipperwort every 4 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with bright indirect light and well-draining, fertile soil with added organic matter. Avoid low spots where water collects after rain.

Integrifolia Slipperwort is suited to USDA Zone 9a – 11b.

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.

Integrifolia Slipperwort can spread to about 1 ft (0.2 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Integrifolia Slipperwort 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.

Integrifolia Slipperwort is frost-tender (hardy to USDA zone 9). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Integrifolia Slipperwort can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to shrubby calceolaria plant care, which shares the same genus.
