Gireoud's Brassia is native to Costa Rica and Panama, in semi-deciduous to evergreen premontane forests, at elevations of 500 to 1000 meters. This plant looks much like the more famous Brassia caudata. The pseudobulbs are elongated ovoid, strong flattened, shiny light green and sometimes 15 cm high and 4 cm wide. Each psodobulb has 2-3 strongly folded, pointed leaves about 30 cm long.
Brassia gireoudiana orchid, also called as Gireoud's Brassia, is a species of the genus Brassia. Several synonyms are know for this species such as: "Brassia verrucosa subsp. gireoudiana (Rchb.f. & Warsz.) Dressler & N.H.Williams 2003"; "Oncidium gireoudianum (Rchb. f. & Warsz.) Rchb. f. 1863". This species was first described by Heinrich Gustav Reichenbach and Josef Ritter von Rawicz Warszewicz in 1854.
IDENTIFY BRASSIA GIREOUDIANA ORCHID
Gireoud's Brassia is native to Costa Rica and Panama, in semi-deciduous to evergreen premontane forests, at elevations of 500 to 1000 meters.
This plant looks much like the more famous Brassia caudata. The pseudobulbs are elongated ovoid, strong flattened, shiny light green and sometimes 15 cm high and 4 cm wide. Each pseudobulb has 2-3 strongly folded, pointed leaves about 30 cm long.
This species blooms in the late spring. The flower stalk appears at the foot of the ripe bulb; sometimes 2 stems per bulb in healthy large plants. The stem is slightly curved and carries 5 to 12 or more sweet-smelling flowers that can be up to 20 cm in diameter. The long thin sepals and petals are yellowish green with pretty many lights dark brown specks and stripes. The lot shorter, in one point, lip has about the same color to which dull-brown speckles at the base.
GROW AND CARE BRASSIA GIREOUDIANA ORCHID
This Brassia species can grow into a large, very attractive plant with a total size of 60 - 100 cm, so you need to take care of this when you grow in the room or the greenhouse.
The plant need a warm temperature and tolerate temperatures only above at least 1°C, require high light level (20.000 - 40.000) lux and should only be screened on the sunniest summer afternoons. You need to keep at least 60% humidity.
Gireoud's Brassia growing in pots, baskets or crates is much better than tied up on a fern block. The most used mixture is 3/4 bark, 1/4 peat moss, but by adding beech leaf and / or baked clay granules (which are also used in hydroponics become even better to get the required permeability. Some growers use styromul (small round polystyrene granules).
Brassia gireoudiana have many thin roots and are quite sensitive to a good moisture / air ratio in it pot mix. It is therefore important to repot on time (every 2 years) in fresh material. In digested potting soil, when the moss begins to gluing, it is soon done with the delicate roots and comes root rot soon. When using shallow baskets or crates, the substrate remains longer good (permeable) because it dries faster after pouring than in a pot.
This species need water regular all year, more abundant during growth, and do not allow the substrate to dry. In the growing season, a normal fertilization of 1 gram inorganic fertilizer per 1 liter of water every 14 days is very conducive to growth.
