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.
