Giant Corpse Flower Plant Care

Giant Corpse Flower (Rafflesia kerrii) belongs to the Rafflesiaceae family within the Rafflesia genus. Giant Corpse Flower is native to the rainforest of southern Thailand and peninsular Malaysia, with notable populations in Khao Sok National Park and Khlong Phanom National Park. Giant Corpse Flower is also known as Corpse Flower.

Giant Corpse Flower displays a large, parasitic plant growth habit, reaching up to 3 ft tall with a spread of approximately 3 ft. Giant Corpse Flower produces massive, foul-smelling flowers.

Leaf size: approximately 15 inches.

Water a young or newly planted Giant Corpse Flower 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.

Giant Corpse Flower thrives in partial shade. Avoid placing Giant Corpse Flower in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Rafflesia kerrii tolerates temperatures of 70–90°F. Giant Corpse Flower prefers humidity levels of 80–100%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, loamy soil with high organic content. Good drainage is essential for Giant Corpse Flower to prevent waterlogging, which leads to root rot and fungal issues.

Feed Giant Corpse Flower every month 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 and rich, loamy soil with high organic content. Avoid low spots where water collects after rain.

Giant Corpse Flower 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.

Giant Corpse Flower can spread to about 3 ft (0.9 m) and reach about 3 ft (1 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Giant Corpse Flower 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.

Giant Corpse Flower 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.

Giant Corpse Flower can be propagated through seeds. Similar propagation techniques also apply to corpse flower plant care, which shares the same genus.

Giant Corpse Flower grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Giant Corpse Flower is native to the rainforest of southern Thailand and peninsular Malaysia, with notable populations in Khao Sok National Park and Khlong Phanom National Park. In cooler regions, grow Giant Corpse Flower as a houseplant or bring it indoors before the first frost.
