Monstera Obliqua

The unicorn of the plant world is a delicate and leathery plant known as Monstera Obliqua, whose paper-thin leaves and textured foliage make it a unique addition to the indoor plant collection. The fenestrated leaves of Obliqua Monstera are not a usual plant feature; this rare-in-rare plant has more holes than leaves! This complex form of obliqua with heavy fenestration is named Obliqua Peru, as it grows in the forests of Peru.

This crown jewel is one of the most expensive plants that are difficult to buy. This beautiful plant with the exotic pattern of its fenestration-dappled leaves is also known as Swiss Cheese Vine due to its close resemblance to holey Swiss cheese.

The large glossy leaves look like those of Philodendron; this is why this exquisite species is also called Philodendron Obliqua. But, it is not a Philodendron at all.

About the Genus Monstera

This genus is a combination of about 48 flowering plant species, all of which are native to central and southern parts of America. The name of this genus, Monstera, has been driven from the Latin word ‘monstrum’ that means unusual or abnormal.  This name suits this species, whose perforated leaves are unique in the plant world.

All of these pretty plants are hemi-epiphytes in nature that depend and grow on other trees. These are mostly grown as houseplants due to their beautiful and delicate foliage. Out of all Monstera plants, Monstera deliciosa bears edible fruit.

Origin and Distribution

This species of the Monstera genus was first collected by Monroe Birdsey in Peru in 1975. After this, it was confirmed by Dr. Michael Madison in 1977.

These exotic plants are primarily found in the tropical regions of America. This includes South America and some parts of Central America. It is also native to Panama, Costa Rica, and Amazon. Because these lovely plants are pretty rare, they are not easily accessible to buy unless you pay a large amount for them.

Monstera Adansonii Obliqua

Monstera Adansonii and Monstera Obliqua are two strikingly similar species. They resemble each other to the extent that you won’t even be able to differentiate between them during their initial growing years.

However, there are three secret ways to know if your plant is Adansonii or Obliqua.

  • If the leaves of your plant are textured and thick, then you have an Adansonii. But if your plant’s foliage is so soft to touch and its leaves are thin as paper, then you luckily have Obliqua Monstera.
  • ‘More holes, less leaf’ is for the unicorn Monstera Obliqua plant; ‘more leaf, fewer holes’ indicate an Adansonii Monstera.
  • The best way to know your plant type is the answer to how easily you got it. If your Monstera Obliqua was easy to get, you probably have an Adansonii. For buying a real and rare Monstera Obliqua Monkey Leaf, you will have to pay a 3 to 4 digits price.

Monstera Obliqua Features

Foliage and Stem

Monstera Obliqua is the slim species of the monstera genus. Its stem is just 2mm thick that can grow about 2-5m in a year. This plant also produces stolons; these stolons are runners that grow horizontally to the next nearest tree, where they can thrive epiphytically.

The foliage is pretty much just holes. Its leaves are thin and smooth. These leaves can reach a size of 10-25 cm. The perforations in leaves vary with the form of oblique complexes. For example, Oblique Peru is 90% holes while Oblique Bolivian is no holes at all!

Monstera Obliqua Variegated

Another feature that makes this plant so rare and unique is that Monstera Obliqua is variegated and dappled. This exotic vine contains a relatively lesser amount of chlorophyll; this variegation gives a unique appearance to Obliqua Monstera. Different patterns of colors appear on the leaves and adorn its foliage.
