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. The plant has a vining habit and often grows entwined in and around itself, with new leaves and vines sometimes growing through the holes in existing leaves. This can lead to leaves tearing which gives the plant a shabby chic rather that pristine appeal.
