Monstera dubia

Monstera dubia is a climbing houseplant native to tropical America, celebrated for the beauty of its juvenile foliage. Its young leaves, pressed flat against their support like tiles, create a green and silver column that will adorn a shelf or a section of wall. This compact and unusual, fairly rare species deserves a place in a bright room with a consistently humid atmosphere.

Originating from the humid tropical forests stretching from southern Mexico to Trinidad and Tobago, through Central America and northern South America, Monstera dubia belongs to the Araceae family. Once described as Marcgravia dubia before being classified under the Monstera genus, it is also mentioned in botanical literature under the synonyms Monstera acreana and Monstera irritans. In the wild, this climber begins its life creeping on the ground before attaching itself to a trunk using its aerial roots, then climbs several metres high.
Indoors, in a large pot, this plant reaches between 1 and 2 m in height depending on the size of its support. Its foliage exhibits dimorphism, a strong difference between the juvenile and adult stages: initially, its leaves are heart-shaped and measure 5 to 10 cm long, they remain tightly pressed against the support and display a silvery marbling with dark green veins. With age and as the plant gains height, the leaves become larger, thicker, and pendulous, they lose some of their silvery pattern and develop lobes and perforations, reminiscent of those of Monstera deliciosa. The inflorescences, rarely seen in our latitudes, are typical of Araceae: a white spike surrounded by a pink spathe.
Like other Monsteras, M. dubia is toxic if ingested due to the presence of calcium oxalate crystals in its tissues.

Indoors, this plant needs light (without direct sun), a warm and humid atmosphere, humidity levels around 60 to 70%, and stable temperatures between 18 and 27 °C. Its cultivation is suitable for an amateur gardener with some experience.
With these precautions, it will thrive in a bright living room, a continuously heated office, or a bright bathroom where shower steam helps it stay lush and green.

Monstera dubia lends itself very well to vertical displays: install it on a moss pole or a raw wood plank, and place it, for example, against a bookcase or the frame of a glazed bay window. It pairs beautifully with the foliage of Calathea insignis, the fine climbing stems of Philodendron scandens, or the magnificent foliage of Philodendron verrucosum. An Alocasia 'Ninja' or another elephant ear with upright leaves will provide a lovely counterpoint to its pressed foliage.
