A cute name for a cute plant and so called due to the (vague?) resemblance of the leaves to that of a cheeky monkey.
A close relative of the Swiss Cheese Plant (Monstera deliciosa), the Philodendron Monkey Mask is often also referred to as Philodendron or Monstera Obliqua, however a true Obliqua is more hole than leaf and nowhere near as attractive as this little chap.
Monstera adansonii is easy to care for so long as it has moist, warm conditions. This plant is trained to grow up a moss pole.
