Ever year, the U.S. Botanic Garden and the Smithsonian Institution Horticultural Services Division put on an great display of orchids, and this year is no exception. Many stunning specimens from the collections are on view, including ‘vintage’ orchid cultivars, some dating back to the turn of the last century. The show is free and runs through April 11 2010 at the US Botanic Gardens on the National Mall in Washington D.C.

Here are a few photos to whet your appetite!

The dendrobiums pictured are mostly spring bloomers requiring a bright, cool and drier winter rest in order to produce their abundant blooms. Many beginner growers have a hard time withholding water for one to two months in order to stimulate flowering. Many of these types of dendrobiums are deciduous-they’ll drop their leaves which also prevents water loss during this ‘rest’ period. The cooler temperatures required during this rest period, about 50 F, also reduces plant growth and hence, water requirement. In fact, they will not produce any new leafy growth until warmer weather, after flowering. Remember also that ambient humidity also tends to be high enough to keep the plant pseudobulbs(long canes) from drying out

  1. Hi Sheetal, thanks. Given the hot humid conditions in Chennai you might want to try phalaenopsis, vandas, or dendrobiums(phalaenopsis type). Given the heat, humidity of 50% or more is essential as is good air movement–enough to keep the foliage constantly moving. Also, provide shady conditions especially during the hottest part of the day. See http://www.ArgusOrchids.net for more basic information on growing orchids. Note: all the dendrobiums photographed here will probably not do well-they need much cooler night temperatures in general.

  2. which orchid can be grown in hot and humid climate in containers.the temp are from 35/40 degrees in summer months.i live in chennai.
