The Swiss cheese plant is a tropical ornamental that has aerial roots growing downwards from the stem. These roots easily once reaching the ground, giving this plant a vine-like tendency. The Swiss cheese plant gets its name from its large, heart-shaped leaves, which as it ages, becomes covered with holes that resemble Swiss cheese. M. adansonii is best grown in a conservatory or greenhouse, where humidity, temperature, and light are all maximized. These are deep-jungle plants that thrive on very high humidity, lots of moisture during the rainy season and high temps. Adult plants are also climbers, so they can be aggressive if grown correctly.
