Coelogyne odoratissima also called as The Fragrant Coelogyne, Coelogyne angustifolia, Coelogyne trifida, Pleione odoratissima, is a species of the genus Coelogyne. This species was described by John Lindley in 1830.
IDENTIFY COELOGYNE ODORATISSIMA ORCHID PLANT
Coelogyne odoratissima is found in southern India and Sri Lanka. It grows in subtropical lower and upper montane forests at elevations of 1000 to 2700 meters above sea level.
It is a as a small sized, cool to cold growing epiphyte with clustered, ovoid to almost round, 2.5 cm tall pseudobulbs enveloped basally by basal sheaths and carrying 2, apical, membraneous, shape variable, elliptic-lanceolate, acute, plicate, 5 nerved, gradually narrowing below into the petiolate base, 10 cm long leaves.
The Fragrant Coelogyne blooms in the late summer and fall on a synanthous, slender, basal, erect, 5 to 10 cm long, simultaneously 2 to 5 flowered inflorescence with persistent floral bracts and carrying waxy, fragrant flowers. The flowers are pure white, the lip having a slight yellow stain in its center.
COELOGYNE ODORATISSIMA ORCHID PLANT CARE AND CULTURE
Cultural information should only be used as a guide, and should be to be adapted to suit you. Your physical location; where you grow your plants, how much time you have to devote to their care, and many other factors, will need to be taken into account. Only then can you decide on the cultural methods that best suit you and your plants.
Light:
Coelogyne odoratissima needs the light level of 20000-30000 lux. In the natural habitat, the strongest sunshine occurs in the winter season, when the sky is clear for more than half the days of each month. Strong air movement should be ensured all the time.
Temperature:
The hottest days of the year occur during the brightest period in late winter and early spring. During this period, the average daily temperature is 24-26 ° C, the night 11-13 ° C, which gives a daily amplitude of 11-14 ° C. In summer, after the start of the rainy season, the average daily temperature is 20-21 ° C, and the night temperature is 11-12 ° C, so the daily amplitude is 9 ° C. During the winter resting period, the average daytime temperature is 18-22 ° C and the nighttime temperature is 8-9 ° C. The daily amplitude is 10-13 ° C.
Humidity:
The Fragrant Coelogyne needs the humidity of almost 85% in summer and early spring, falling to 60-70% at the beginning of winter. The driest period is the end of winter and the beginning of spring before summer monsoon rains, but in mountainous habitats, the conditions are probably not as dry as the climate stations at lower altitudes.
Too dry air has a negative effect on the development of the plant: its growth is inhibited, and the leaves begin to turn yellow and dry out. The higher temperature, the higher the humidity should be, and the higher the humidity, the more often and longer it is necessary to ventilate the room where the plants are contained, otherwise the probability of rotting and various kinds of fungal diseases.
Substrate, growing media and repotting:
Coelogyne odoratissima grows best attached to pieces of tree fern or cork, but during the summer hot and sunny days it requires high humidity and several waterings during the day. The plants, however, are usually planted in shallow containers or baskets which allow the drooping racemes to hang over the sides (but they do well enough in pots), because for most growers it is difficult to maintain high humidity in the summer planted on rootstocks. The substrate should be loose, quickly draining water, but at the same time it must stop a large part of it, not soaking excessively and not decomposing too quickly. A mixture of chopped tree fern fibers mixed with 10% perlite, 10% cut sphagnum moss and 10% charcoal gives great results for most growers and this medium undergoes very slow decomposition. It is also possible to use a fir bark, if humectants are added, but the constantly moistened bark decomposes quickly and the plants need to be replanted more often.
The plant should be replanted as little as possible, because this shock may even stop flowering for the next three years, which is why slowly decomposing substrates are so desirable. Some believe that as long as the substrate is still loose and well-aerated, it is better to simply cut old, drying pseudobulbs than to replant the plant. However, if replanting is necessary, it is best to do it when new roots begin to grow. This will allow the plant to adapt to the new substrate in the shortest possible time.
Watering:
The Fragrant Coelogyne should be abundantly watered during active growth, with little drying between waterings, although this drying is not necessary. Watering is directly dependent on the temperature of the content, the higher it is, the more often it needs to be watered. When watering, excess water should flow freely from the pot, since stagnation of water both inside the pot and in its pan can very quickly lead to rotting of the roots and the lower part of the plant.
Fertilizer:
During the active growth, the plant should be fertilized every week 1/4-1/2 of the recommended dose of fertilizer for orchids. Many breeders prefer to use sustainable fertilizer throughout the year, but there are also those who use fertilizer with increased nitrogen content from spring to mid summer, and then, in late summer and autumn, begin using a fertilizer with a higher content of phosphorus.
In order to avoid the accumulation of mineral deposits during the period of strong fertilization, it is recommended to rinse the containers approximately every month. Flushing is especially important where the water is highly mineralized. First, normally, the plant should be watered to dissolve the accumulated salts, and after about an hour, rinse the substrate with water equal to twice the volume of the container.
Rest period:
When new growths reach maturity in autumn, the amount of water supplied decreases gradually, and in winter only small occasional watering or morning spraying is enough. The amount of water can be increased when we notice the drying of the tips of the youngest leaves or when the pseudobulbs become wrinkled excessively. Leaves on older pseudobulbs may naturally die in this period, but the ends of the youngest should remain green. A small wrinkle can also occur on the newest pseudobulbs. Over wrinkles indicate a shortage of water, while its lack, i.e. excess water, can cause the plant to not bloom. When new roots begin to grow in spring, this is a sign to gradually increase the amount of water supplied.
