Spirabutilon citrinum Plant Care

Spirabutilon citrinum (Spirabutilon citrinum) belongs to the Malvaceae family within the Spirabutilon genus.

Spirabutilon citrinum displays an upright, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Spirabutilon citrinum produces bell-shaped flowers in various colors like pink, red, or orange.

Leaf size: approximately 4 inches.

Water a young or newly planted Spirabutilon citrinum 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.

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

Spirabutilon citrinum tolerates temperatures of 65–75°F. Spirabutilon citrinum prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, loamy soil with added compost for nutrients. Good drainage is essential for Spirabutilon citrinum to prevent waterlogging, which leads to root rot and fungal issues.

Feed Spirabutilon citrinum 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.

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, loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Spirabutilon citrinum is suited to USDA Zone 13b.

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.

Spirabutilon citrinum can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Spirabutilon citrinum 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.

Spirabutilon citrinum 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.

Spirabutilon citrinum can be propagated through softwood cuttings, seeds.

Spirabutilon citrinum grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. In cooler regions, grow Spirabutilon citrinum as a houseplant or bring it indoors before the first frost.
