Giant Calla Lily Plant Care

Giant Calla Lily (Typhonodorum lindleyanum) belongs to the Araceae family within the Typhonodorum genus. Giant Calla Lily is native to Madagascar, the Comores, Zanzibar, Réunion and Mauritius. Giant Calla Lily is also known as Lindley's Typhonodorum.

Giant Calla Lily displays a low rosette, clumping growth habit, reaching up to 2 ft tall with a spread of approximately 2 ft. Giant Calla Lily produces small, inconspicuous flowers surrounded by a large, showy spathe.

Leaf size: approximately 12 inches.

Water a young or newly planted Giant Calla Lily 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.

Giant Calla Lily thrives in bright indirect to low light. Avoid placing Giant Calla Lily in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Typhonodorum lindleyanum tolerates temperatures of 65–80°F. Giant Calla Lily prefers humidity levels of 60–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining peat-based mix with perlite and orchid bark. Good drainage is essential for Giant Calla Lily to prevent waterlogging, which leads to root rot and fungal issues.

Feed Giant Calla Lily 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.

Choose a spot with bright indirect to low light and rich, well-draining peat-based mix with perlite and orchid bark. Avoid low spots where water collects after rain.

Giant Calla Lily is suited to USDA Zone 10b – 12b.

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 Calla Lily can spread to about 2 ft (0.6 m) and reach about 2 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 Giant Calla Lily 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 Calla Lily is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Giant Calla Lily can be propagated through division, offsets, seeds.

Giant Calla Lily grows outdoors in USDA Zone 10b – 12b. It survives winters down to planting zone 10b. Giant Calla Lily is native to Madagascar, the Comores, Zanzibar, Réunion and Mauritius. In cooler regions, grow Giant Calla Lily as a houseplant or bring it indoors before the first frost.
