It is a genus of epiphytic orchids, about twenty, originating from central-southern America. It has consistent pseudobulbs, of medium size, which produce one or two oval, elongated, fleshy, dark green leaves; in spring and summer it produces small thin stems, at the apex of which a single cup flowers, shaped like a cup, with the sepals widened and facing backwards. The flowers of this orchid trigonidium are generally pale in color, cream yellow or sometimes even pink; some species have numerous dark brown or iridescent streaks of great visual effect. The bearing of the Trigonidium orchid is rather erect and columnar, of a shrub type; during the whole year the leaves are always shiny and green, being an evergreen species.
The Trigonidium orchid loves very bright positions, but, especially in summer, it is good to keep it away from the sun's rays that could irreparably damage the leaves and flowers of our beautiful orchid; it is a species that fears the cold very much and the ideal temperature of cultivation is between 15-25 ° degrees, all year round, so it is good to protect it from cold in winter and from heat in summer. In the colder months of the year it can be kept indoors or in a temperate greenhouse, leaving it even in full sun. Some species of maxillaria originate from mountainous areas and therefore bear temperatures even lower than 10 ° C but only this kind of orchids. For the other varieties, the rules shown above apply.
The watering of our orchid must be abundant, without, however, leaving the roots and the pot in contact with water for too long, so it is advisable to place the plant in a saucer filled with pebbles, perlite or expanded clay, taking care to always leave a little water on the bottom. To obtain a better flowering it is advisable to reduce watering from the moment the buds appear, until the flowers have completely withered. Provide appropriate fertilizer for orchids mixed with the water of the waterings, avoiding to exceed the doses and remembering that it is preferable to supply fertilizer several times in small quantities rather than providing abundant quantities of fertilizer sporadically.
The soil is one of the most important elements to consider for the cultivation of our beloved plant species. This is because the plants acquire the main nutrients they need to develop and grow healthy and vigorous. These orchids need an ad hoc compost, made up of barks, sphagnum moss and other light and incoherent materials, which help us simulate natural growth conditions. With this particular soil mixture, our orchids will be able to develop at their best and show all their elegance and beauty.
The multiplication of the Trigonidium orchid occurs by dividing the tufts of pseudobulbs, which in spring can be buried in individual containers to obtain new plants.
