monstera, (genus Monstera), genus of nearly 50 species of flowering plants of the arum family (Araceae), native to tropical America. Several are grown as popular ornamental foliage plants. Monstera plants are generally climbing and can be terrestrial or epiphytic. They have attractive leathery leaves that are often cut into lobes.
The Swiss cheese plant, or Mexican breadfruit (Monstera deliciosa), is a common houseplant with showy, glossy, perforated leaves slashed to the margins; numerous horticultural varieties have been developed. When fully ripe, its sweet scaly fruit is edible and tastes like a combination of pineapple and mango. All other parts of the plant, including the unripe fruit, contain calcium oxalate and are considered mildly toxic if ingested by humans.
