The Dossinia marmorata orchid is a species of terrestrial orchid native to the Philippines. It is valued for its white-marbled green leaves, as well as its pink or purple flowers, which can appear throughout the year.

The leaves of Dossinia marmorata are succulent, that is, they are able to store water. They are also oval, slightly pointed at the end and about 10 to 15 cm in length. The white mottling on the leaves can vary in size and shape between individuals.

The flowers of Dossinia marmorata are borne on stalks which can measure up to 30 cm in height. They are relatively small, measuring only a few centimeters in diameter, and are often arranged in clusters. The flowers are usually pink or purple in color, with darker spots in the center of the lip.

To keep Dossinia marmorata healthy, it is important to provide it with growing conditions suitable for its natural habitat. This orchid prefers shaded areas with medium to low light. It tolerates temperatures ranging from 18 to 25°C during the day, but prefers cooler temperatures at night. It can also tolerate lower temperatures during the winter months, but it is important to protect it from frosts.

The growing medium should be well-drained and slightly acidic, such as a mixture of sphagnum moss and perlite. It is important to keep the substrate moist, but not soggy, as excessive moisture can cause root rot problems. Watering should be regular, but moderate, avoiding letting water stagnate in the bottom of the pot.

Dossinia marmorata can be fertilized every two weeks with a balanced houseplant fertilizer. However, avoid over-fertilizing as this can cause root and leaf burn.

In summary, the optimal conditions for cultivating Dossinia marmorata are:

Medium to low brightness

Moderate temperatures ranging from 18 to 25°C during the day

A well-drained and slightly acidic growing medium

Regular and moderate watering, with a moist but not soggy substrate

Fertilize every two weeks with a balanced fertilizer for indoor plants
