About Cecropia pachystachya

Cecropia pachystachya, known as Ambay or pumpwood, is a fast-growing tree native to South America, notable for its large lobed leaves and hollow trunk. Its dense foliage and branched form give it a tropical and exotic appearance, ideal for large gardens or as a shade tree in warm climates. It attracts wildlife, especially birds, which feed on its fruits.

Native range

South America, including Brazil, Argentina, Paraguay, and Uruguay.

Care tips

It requires full sun to partial shade exposure and well-drained soil, preferably rich in organic matter. Watering should be abundant during warm months, reducing it in winter, but avoiding waterlogging as it is susceptible to root rot. It is essential to protect it from frost, as it does not tolerate sub-zero temperatures. A common mistake is planting it in small pots, restricting its rapid growth and final size.
