Monstera deliciosa: the holes come as standard

Monstera deliciosa is a climber from the wet tropics, native to a region Kew identifies as Mexico to Guatemala. Adult leaves are broad, with splits along the edges and openings inside. Aerial roots help it climb: its original setting was a forest, rather than a living room. [1][2]

Young plants usually have leaves without the characteristic holes; as they mature, they can produce new leaves with openings. To observe the difference, compare a small leaf with a more developed one without cutting anything. Those natural perforations need no scissors: the plant runs its own graphics department. [3]
