Gardenia gordonii Plant Care

Gardenia gordonii (Gardenia gordonii) belongs to the Rubiaceae family within the Gardenia genus. Gardenia gordonii is native to Fiji.

Gardenia gordonii displays a compact, evergreen shrub growth habit, reaching up to 4 ft tall with a spread of approximately 4 ft. Gardenia gordonii produces fragrant, white, waxy blooms.

Leaf size: approximately 4 inches.

Water a young or newly planted Gardenia gordonii every 7–14 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.

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

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

Well-draining, acidic soil mix with added peat moss and sand. Good drainage is essential for Gardenia gordonii to prevent waterlogging, which leads to root rot and fungal issues.

Feed Gardenia gordonii 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, acidic soil mix with added peat moss and sand. Avoid low spots where water collects after rain.

Gardenia gordonii 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.

Gardenia gordonii can spread to about 4 ft (1.2 m) and reach about 4 ft (1 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Gardenia gordonii 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.

Gardenia gordonii 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.

Gardenia gordonii can be propagated through softwood cuttings, air layering, seeds. Similar propagation techniques also apply to gardenia plant care, which shares the same genus.

Gardenia gordonii is susceptible to aphids, whiteflies, scale insects. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

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