The Shape of the Holes

Monstera Obliqua Peru is the most well-known of the Obliqua complex. However, they do start with no to very few fenestrations and will fenestrate more as they grow.
To make it even more confusing there are lots of Monstera Obliqua that have no holes at all as the number of holes is not a defining factor of a Monstera Obliqua.

How to Spot the Rare Kind of Monstera Adansonii – The Variegated Monstera
Variegation is a term used to denote the appearance of white or yellow splashes on the leaves, stems, or stalks. The appearance of variegation in plants is rare.
Hence, if you want to purchase a variegated Monstera Adansonii, be ready to pay big bucks.
Variegation can appear as a mutation, part of genetics, or lack of chlorophyll pigment. There are two types of mutation. One is random; the other is genetic (also known as chimeric).
Discoloration vs. Variegation
Discoloration does not equate to variegation. Most times, the discoloration that most plant owners misunderstand variegation for is actually a side effect of a disease named Mosaic Virus or malnutrition.
Causes of Variegation
Genetic mutations are one of the causes of variegation. It is characterized by the absence of the green pigment named chlorophyll.
This occurs due to the disruption in the biochemical process of chloroplast biogenesis. Random mutations are another reason for variegation. Albeit it is very common, it is the most unstable form.
How to Care for a Monstera Adansonii
Your Monstera Adansonii can survive low humidity levels, such as those of an in-home environment. However, they grow best in humidity levels above 60%.
Overwatering is a common mistake made by new Monstera owners. Monstera Adansonii requires lightly moist soil and needs to dry out slightly before re-watering is necessary.
Monstera Adansonii grows best in temperature ranges of 60-80 degrees Fahrenheit (15.6-26.7°C). Any temperature below 60 degrees Fahrenheit (15.6°C) will slow down the growth rate exponentially.
Monster Adansonii is a climber by nature. Hence, it will require additional support if it is to climb. You can use moss poles, trellises, and stakes to support your Monstera.
