Titan arum: complete guide

Overview

Titan arum (Amorphophallus titanum), also called the Corpse Flower, is one of the most fascinating and bizarre plants in the world. The plant is famous for its colossal inflorescence, one of the largest unbranched floral structures known. It produces a characteristic strong putrid odor resembling rotting flesh. The plant is native to the rainforests of western Sumatra. It is a rare plant typically cultivated only in botanical gardens and by serious enthusiasts.

Appearance and Bloom

Titan arum produces the world's largest unbranched inflorescence, sometimes exceeding 3 meters in height. The floral structure consists of a massive dark purple to burgundy spathe surrounding a thick spadix column. Prior to flowering, the plant produces gigantic deeply lobed triangular leaves reaching 4-6 meters in height. The inflorescence emits a powerful stench resembling rotting flesh and carrion, which attracts carrion-feeding flies and beetles for pollination. The bloom lasts only hours to a maximum of two days.

Ideal Location

Titan arum thrives only in consistently warm, very humid tropical conditions: minimum 20-25C. This is strictly a greenhouse plant in temperate climates. The plant tolerates shade and prefers rainforest-like conditions with very high humidity. Provide ample space for the enormous growth.

Soil

Use well-draining potting soil with abundant humus, peat, and compost. Ensure perfect drainage. Large containers required: 100L+ minimum. Slightly acidic to neutral pH preferred.

Watering

During active growth: keep soil consistently moist but never waterlogged. Mist foliage regularly. During dormancy (winter): reduce watering almost entirely.

Pruning

No pruning necessary. Remove only dead leaves.

Maintenance Calendar

• March/April: Corm awakens, begin watering
• May-September: Active growth period, maximum water and humidity
• October/November: Gradually reduce watering
• December-February: Dormancy, minimal water, cool conditions

Winter Hardiness

Titan arum is strictly tropical and cannot tolerate cold. Winter cultivation requires heated greenhouse or indoor conditions.

Companion Plants

This is best grown as a solitary specimen where it can dominate. It is extremely challenging to cultivate at home and better suited to botanical gardens.
