It is a kind of epiphytic orchid with high ornamental value because of its unique flower pattern. Pseudobulbs are oblate, racemes extruding from pseudobulbs, labellum purplish black with yellow stripes, distally located at flowers, inverted to form a scallop-like covering style; The flowers open in succession and bloom for four to five months.
Clamshell Orchid grows in forests ranging from sea level to 2,000 m above sea level, and in its native regions, from low tropical elevations to cool alpine regions. Different species in different places of origin have different requirements on cultivation environments. Low tropical species and hybrids usually without significant dormancy; The cultivars at high altitudes had obvious dormant periods. All species of this genus require sufficient moisture and high air humidity during the growing season. The plants of Clamshell Orchid have a large volume and need a large amount of fertilizer during the vigorous growth period, so they need to apply liquid compound fertilizer once every 1-2 weeks. Clamshell Orchids also like bright sunlight and grow weakly and flower poorly in lack of sunlight.Summer sunny shading amount %50 or so, winter north is not fast overcast.
Place clamshell orchids in bright, oblique sunlight. One proper choice is an east-facing window the place the plant is uncovered to morning daylight however blanketed from warm afternoon solar that may additionally scorch the leaves. You can additionally area the plant underneath fluorescent bulbs.
Clamshell orchid flowers don’t do nicely in extraordinarily excessive temperatures. Ensure room temps are beneath eighty five F. (29 C.), and at least 15 stages cooler at night. Water: As a widespread rule, clamshell orchid plant life wants water about as soon as each and every week or now and again a little extra often, the usage of tepid water or rainwater. Allow the soil to come to be nearly dry between watering. Reduce moisture throughout the wintry weather months.
Feed clamshell orchid plant life each different week at some point of the developing season the use of a balanced, water-soluble fertilizer with an NPK ratio such as 20-20-20. Feed the plant solely when the soil is moist. Withhold fertilizer for the duration of the winter.
Repot the plant when the container turns into too snug. The satisfactory time for repotting orchids is quickly after a new boom seems in spring. Humidity: Clamshell orchid vegetation decides on a humid environment. Place the pot on a tray of damp pebbles to enlarge the humidity round the plant. Mist the orchid on occasion when the air is dry.
Under normal circumstances, the use of sub-plant reproduction, more in the spring plant exuberant growth before, potted 2 ~ 3 years and has been overgrown pot plant sub-plant. When dividing Clamshell Orchid, first remove the plants from the pot; Remove the old substrate, and remove the dry leaves, old pseudobulbs, and dead roots. Then cut the Clamshell Orchids into clusters, careful not to touch the new buds and roots. At least 3 pseudobulbs are left in each cluster after cutting, so that the flowering of the plants after cutting will not be affected in the same year. Usually use fine grain weathered volcanic rock, bark, fire soil, etc., as a matrix potting, pay attention to the potting to make the side of the new bud toward the basin edge, and leave 2 ~ 3 years of growth space for the new bud. Plant planting depth should be slightly lower than the base of the pot substrate surface, not too deep or too shallow. Place the half shade after potting, 3 ~ 5 days without watering, let the wound healed and prevent the cause of rot; Just a small amount of water on the leaf daily to keep the plant dry. After the new roots and shoots enter the normal growth, they can be cultivated and managed as normal as other plants. Tissue culture method or aseptic seeding method can be used in mass production, but certain facilities and operating techniques are needed.
Clamshell Orchid has more than ten kinds of common, at present our country market common kinds have the following several kinds.
United States of Florida and western Andes from Mexico to Colombia and Venezuela, growing from sea level to elevation of 2000m.
