Swamp taro (Cyrtosperma hayii)

Product description

This swamp taro belongs to the arum family (Araceae) and is native to the swamp forests of New Guinea and the surrounding islands. Like other species within the genus, this plant grows in very wet conditions, often along rivers or in low-lying areas that are regularly flooded. The species produces large, arrow-shaped leaves on sturdy petioles and, under favourable conditions, can grow into a beautiful houseplant. Relatively little is known about the exact ecology of this species, given that it was only described in 2024.

It is a tropical species that grows best at high temperatures (25–30 °C) and high humidity. Ensure the soil is very moist to wet; the plant can even stand with its roots in a shallow layer of water. A well-aerated substrate rich in organic matter, such as peat, coconut fibre or sphagnum, works well. Place the plant in a bright spot without direct sunlight. The species develops an underground root system (rhizome) from which new shoots emerge. This allows the plant to spread gradually when conditions are favourable.

Sowing instructions: Germinated seeds can be placed directly into a very moist sowing mix. This can consist of potting soil mixed with additional organic material such as sphagnum or coconut fibre. Keep the soil constantly moist and maintain a temperature of around 25–30 °C to ensure good further development.
