Typhonodorum lindleyanum or Water Banana has a truly striking appearance: the looks of a banana plant with large leaves like a taro.
It is a member of the arum family and is the only member of the genus Typhonodorum.
In the tropics, it can grow in the garden throughout the year. In temperate regions you can treat it as an orangery plant: indoors in winter and outdoors in summer. It can also be grown as a houseplant or in a heated greenhouse.
In the tropics, this is an invasive species.
Typhonodorum lindleyanum is an herb with numerous leaves that grows up to 2-4 m tall, with a fleshy creeping rhizome.
The pseudostem is formed by brown, dead leaf sheaths. The projecting portion of the petiole is 30-100 cm long, green and succulent. The leaf is subtriangular to arrow-shaped, light green, 70-140 cm long and 55-85 cm wide. The leaf discs of young plants are narrower. The midrib is quite wide: 1-1.5 cm at the base.
The petiole is erect, 40-50 cm long and 3 cm in diameter. After flowering, it hangs down. The spathe is 45-80 cm long, narrowed between the male and female flowers, rolled up to form a tube towards the base. The spadix is yellow, 35-55 cm long and 3 cm in diameter. Blooms throughout the year.
The infrutescence is 17 cm long and 12 cm in diameter, the spathe becomes green, then putrid at maturity of the fruit. The fruit is a spherical to ovoid berry, 4 cm in diameter, bright yellow, with one and sometimes two seeds. The seeds are flattened, 3×3 cm and 1.5 cm thick, greenish brown.
- fruits and rhizome are poisonous but eaten locally after prolonged boiling
