Coelogyne Rochussenii

coelogyne Rochussenii

Coelogyne (necklace orchids)

Coelogyne is a genus of over 200 sympodial epiphytes from the family Orchidaceae, distributed across India, China, Indonesia and the Fiji islands, The genus is abbreviated Coel in trade journals.
The wide distribution of this genus has resulted in a wide variety of temperature variation from species to species, some requiring cool to cold conditions to grow and bloom reliably, while others need decidedly warmer temperatures to achieve the same.

They have often a sweet scent, attracting different kinds of pollinators, such as bees, wasps and beetles.

A few species are commonly known as ‘necklace orchids’, because of their long, pendant, multi-flowered inflorescence.
Coelogynes could be divided to two big groups – so called “Cool” Coelogyne group and “Warm” Coelogyne group.
Cool Coelogynes:- come from mountain cloud forests of Himalayan, in nature they have warm but misty and cloudy summers and cool to cold but extremely sunny winters. Such Coelogynes such as large-flowered and extremely showy Coelogyne cristata, Coelogyne mooreana, Coelogyne mossiae, lovely Coelogyne fimbriata, Coelogyne nitida and Coelogyne corymbosa.
Warm Coelogyne group.:- They grow in much warmer biomes such as tropical rainforests, so they are more suitable for indoor growing because they do not need cold temperatures to grow and bloom. They are mostly epiphytes or lithophytes and occasionally terrestrials. Species such as Coelogyne speciosa, Coelogyne lawrenceana and Coelogyne salmonicolor with large single flowers, which have fancy lips need intermediate to warm temperatures, half shade to filtered bright light, moderate watering and fertilizers. Substrate should be epiphytic (medium bark) with some elements with high water capacity such as sphagnum moss. They have no definite dormancy period and simply need some reducing of watering after pseudobulbs had been formed.

 

coelogyne Rochussenii

Coelogyne rochussenii is a warm-growing, pendulous flowering orchid from low tropical areas of Singapore, Malaysia, Thailand and the Philippines.
It is really common in Singapore under cultivation and forms huge spectacular specimens with almost a curtain of pendulous spikes of flowers all around the pot.
Description

Plants bloom throughout the year with forty 6.25 cm wide flowers. Flowers can be fragrant with the scent of lemon.It’s grown for its handsome evergreen foliage and for its long draping clusters of fragrant, pale lemon-yellow blooms.Clusters of 20 to 40 buff-yellow blooms are borne on long dangling stems that sprout from the bases of old pseudobulbs in winter. Each blossom has five lance-shaped “petals” and a central creamy-white lip. The lip is marked with several yellow ridges and two brown bands.
Culture
Plants are usually grown in baskets. Plant grows in intermediate to warm temperatures with partial shade ( bright indirect or filtered light ).
Water regularly through the year. Pot in a well drain medium.

They have no definite dormancy period and simply need some reducing of watering after pseudobulbs had been formed.

Coelogyne nitida

Coelogyne nitida is a cool-growing species originating in the Himalayan region of India and southeast Asia. It requires a decided rest period during winter during which it receives no feed, very little water (enough to prevent pseudobulbs shrivelling), cool to cold temperatures and high light. These conditions seem to aid flowering in spring for some growers, though others report that more constant conditions can also produce regular flowering.

TEMPERATURES:

Plant grows in cool to intermediate average temperatures ranging from 18.89°C to 1.67°C. .

Summer days average 18-19C, and nights average 13-14C with a diurnal range of 5C.
Plants adapt to warmer afternoon temperatures if humidity is kept high, if air movement is
strong, and if the plants are able to cool down in the evening.
Humidity

85-95% most of the year, dropping 75-80% from late autumn into
spring. Strong air movement should be provided at all times.
shade

require partial shade from 1500 to 2500 foot . Plants should not be exposed to direct midday sun.
WATER:

plants should be watered heavily while actively growing, but the medium must not be allowed
to become stale or soggy. Water should be reduced after new growths mature
in autumn.
Media
Plants are usually grown in baskets.This orchid grows on mossy trees and rocks in an area of high rainfall so it should be given a good draining medium that stays moist but not wet. As with all epiphytes this orchid can be mounted but in dry conditions extra care should be taken to maintain appropriate moisture levels.

REST PERIOD:
Winter days average 8-9C, and nights average 2-3C, with a diurnal range of 7C.Water should reduced for cultivated plants in winter, but
they should not be allowed to remain dry for long periods. In most growing
areas, a light watering every 3weeks or so with occasional mistings
between waterings will meet the plant’s requirements. The cool, dry rest
is essential for healthy growth and flowering, found that low temperatures of 9-10C along with reduced water for
about 3 months is sufficient to meet the rest requirements.
