    Amorphophallus: Care and Dormancy Guide

    What Is Amorphophallus?

    Amorphophallus is a genus of tuberous aroids famous for their bizarre and beautiful growth. Each tuber typically produces a single, tall, umbrella-like leaf on a mottled stem, followed by a period of dormancy. Amorphophallus konjac is one of the most widely grown, while the titan arum is legendary for producing one of the largest flowering structures in the plant kingdom. Patterned-stem species such as Amorphophallus atroviridis are prized by collectors.

    How to Care for Amorphophallus

    Amorphophallus grow actively in the warmer months and go dormant in winter, dying back to the tuber. During growth they enjoy warmth, bright indirect light and a rich, free-draining mix kept lightly moist. When the leaf yellows and dies back, reduce watering and keep the dormant tuber barely moist and warm until it reshoots. This natural cycle is normal and not a sign of a problem.

    Frequently Asked Questions

    Amorphophallus is a genus of tuberous aroids grown for their dramatic single leaf and, in some species, their extraordinary flowers.

    They include the famous titan arum and the easier Amorphophallus konjac.

    Dieback is completely normal. Amorphophallus are seasonally dormant, dying back to the tuber after their leaf has run its course.

    Reduce watering, keep the tuber barely moist and warm, and it will reshoot when it is ready.

    During active growth, give them warmth, bright indirect light and a rich, free-draining mix kept lightly moist.

    When the leaf dies back, keep the tuber warm and nearly dry until new growth appears.

    Some Amorphophallus, most famously the titan arum, produce a strong carrion scent when in flower to attract pollinators.

    Most species are grown for their striking foliage and flower only rarely indoors.

    Typically Amorphophallus produce one new leaf per growing season, often larger than the last as the tuber matures.

    Between leaves the plant rests as a dormant tuber.

    As aroids, Amorphophallus contain calcium oxalate crystals and are not considered safe for cats or dogs if chewed.
