Adanson's Monstera
Monstera adansonii (mon-STER-ah ah-dan-SOHN-ee-eye)
The Swiss Cheese Plant is a tender, evergreen, herbaceous perennial climber that hails from the tropical rainforests of Mexico, Central America, and South America. In its native habitat, it uses aerial roots to attach itself to a large tree so it can climb upwards to have access to more sunlight. It is a popular houseplant with large, medium to dark green, heart-shaped leaves and unique oval holes. The holes in the leaves help sunlight to filter down to the plant. Using a trellis or moss pole, an Indoors plant can reach up to 3 to 8 feet tall and 1 to 3 feet wide. It can grow 10 to 13 feet when grown outdoors. This plant prefers bright, indirect sunlight and warm, humid conditions. Direct sun can cause scorched leaves. Moist, well-drained soil with a slightly acidic pH is recommended. Avoid cold drafts and temperature drops below 50 degrees Fahrenheit. The plant prefers high humidity; consider using a humidifier or placing the container on a tray of wet pebbles. It is hardy in USDA Zones 10 to 12. Be sure to provide a stake, trellis, or moss pole in the center of the container to give the plant a structure to climb upon.
