Upright Calceolaria Plant Care

Upright Calceolaria (Calceolaria stricta) belongs to the Calceolariaceae family within the Calceolaria genus. Upright Calceolaria is native to Ecuador.

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

Leaf size: approximately 2 inches.

Water a young or newly planted Upright Calceolaria 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.

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

Calceolaria stricta tolerates temperatures of 60–75°F. Upright Calceolaria 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 Upright Calceolaria to prevent waterlogging, which leads to root rot and fungal issues.

Feed Upright Calceolaria 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.

Upright Calceolaria 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.

Upright Calceolaria 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 Upright Calceolaria 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.

Upright Calceolaria 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.

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

Upright Calceolaria is susceptible to aphids, whiteflies, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Upright Calceolaria grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Upright Calceolaria is native to Ecuador. In cooler regions, grow Upright Calceolaria as a houseplant or bring it indoors before the first frost.
