Siam Villa Garden: Swiss Cheese Plant

This member of the arum family (Araceae) is a hemiepiphyte with aerial roots. It is able to grow up to 20 m (66 ft) high in the wild, with large, leathery, glossy, pinnate, heart-shaped leaves 25–90 cm (10–35.5 in) long by 25–75 cm (10–29.5 in) broad. The leaves on young plants are smaller and entire with no lobes or holes, but soon produce lobed and fenestrate leaves as they grow. Although it can grow very tall in nature, it only measures between 2 and 3 m (6.6 and 9.8 ft) when grown indoors. The older the plant, the more the leaves are covered with its familiar large perforations.

Wild seedlings grow towards the darkest area they can grow until they find a tree trunk, then start to grow up towards the light, creeping up the tree.

Monstera deliciosa is commonly grown outdoors as an ornamental plant in the tropics and subtropics. The plant requires a lot of space and a rich and loose soil (ideally garden soil and compost in equal parts). If it grows in the ground it is better to plant it near a tree, where it can climb, if not against a trellis. It is moderately greedy and needs to be watered just to keep the soil slightly moist. Its hardiness is 11 (that is to say the coldest at −1 °C or 30 °F). It cannot withstand these temperatures for more than a few hours, but it can live outside in certain temperate regions (Mediterranean coast, Brittany). A steady minimum temperature of at least 13–15 °C (55–59 °F) is preferable, allowing continuous growth. Growth ceases below 10 °C (50 °F) and it is killed by frost. It needs very bright exposure, but not full sun.

Forcing a M. deliciosa to flower outside of its typical tropical habitat proves to be difficult. Specific conditions need to be met for the plant to flower. However, in its tropical and subtropical habitat, the plant flowers easily. In ideal conditions it flowers about three years after planting. The plant can be propagated by taking cuttings of a mature plant or by air layering.

Medical Uses

Roots of monster fruit (or sometimes the leaves) are used in Mexico to make an infused beverage used to treat arthritis.

Inhabitants of the Caribbean island of Martinique prepare a cure for venomous snakebites from the roots of the monster fruit.

Wounds are sealed with a paste made from the mashed leaves of monster fruit in Brazil.

Chinese believe that various parts of the plant are an effective cure for a number of diseases, like bruises, cough, fever or some types of infection.

Due to high dose of potassium and vitamin C, a smoothie prepared from monster fruits is quite popular among sportsmen who want to have more stamina and raise their energy levels.

It also provides a useful mix of nutrients to cancer patients who recover after a period of radiotherapy.
