This charming vining plant is famous for the unique holes, or fenestrations, that develop in its leaves as it matures. It loves to climb, so providing a moss pole will encourage larger, more dramatic foliage. It is a fantastic choice for adding a tropical feel to your home.

Grows well with

  • Pothos They share similar care requirements for light, water, and humidity, making them easy to group together.
  • Philodendron Many philodendrons have comparable needs and aesthetic qualities, complementing the Monstera.
  • Ferns Ferns often appreciate the high humidity that Monstera adansonii also prefers, creating a lush understory effect.

Similar species

  • Monstera deliciosa While larger, M. deliciosa shares the characteristic fenestrated leaves and similar vining growth habit, differing mainly in leaf size and hole pattern.
  • Rhaphidophora tetrasperma This plant, often called 'Mini Monstera,' has deeply lobed leaves that resemble fenestrations and a similar climbing habit, though it belongs to a different genus.

How often should I water it?
Water when the top inch or two of soil feels dry. Avoid letting it sit in water.
Does it need high humidity?
Yes, Monstera adansonii thrives in high humidity, so misting, using a humidifier, or placing it in a bathroom can be beneficial.
Can it be propagated easily?
Yes, it can be easily propagated from stem cuttings placed in water or soil.

Where the name comes from

The genus name 'Monstera' comes from the Latin word for 'monster,' likely referring to the plant's large, unusual leaves. 'Adansonii' honors the Scottish botanist Michel Adanson.

Good to know

  • It's a hemi-epiphyte in its natural habitat, starting life on the ground and then climbing trees.
  • The holes in the leaves help the plant catch more sunlight as it grows upwards.
  • This plant is native to Central and South America.
  • New leaves unfurl from a protective sheath called a cataphyll.
