    Default Renanthera imschootiana

    I have had this orchid for about 2 years. Last year I gave it some direct morning light with shaded evening sun. It grew but no flowering. This year I gave it lots of late evening sun. I grew 3 shoots but as the weather began to get warmer I think it received too much direct light because the flowers bud didn't look healthy. I moved it so it received less light and although there are flowers beginning to open it doesn't appear all of the flowers will open. Here is a closeup of a couple that managed to open.Trial and error I guess.Name:  renanthera - 1.jpg

    What good flowers these are ; much better colour and markings than I have seen. But Ren's are rarely seen in UK. I used to have half a dozen plants, ( species and hybrids - but apart from the yellow one, and also monachica, they all looked the same )and since the flowers lasted a couple of months, and they usually flowered twice a year, I always had a plant to put in a show, and they attracted a lot of attention because of their rarity in UK. I found them quite easy, growing in my greenhouse which was then set to a night minimum temperature of about 16 or 17, and with several layers of 50% shade cloth in the summer,the plants being sprayed with rain water most days.sometimes, in sunny weather several times a day , in attempts to keep the temperature down to 30 or so - it also needed the doors left wide open to succeed, but usually if I did that I could keep those temperatures. Problems came if I was away from home for a week or more, or when other matters ( like my wife in intensive care) meant that they were not touched or looked at for a couple of weeks at a time. Eventually, after serious overheating in such spell of personal problems, a lot of plants suffered serious heat damage, and I scrapped most of the Rens. Kept just a couple - and now with the thermostat set to 12 or 13 instead of 16 or 17, they are growing slower, but I have a couple of spikes developing. I shall find it interesting tosee if my flowers are better at the current lower temperatures.

    Beautiful shots of a lovely Ren. Renanthera have always been very difficult to grow for me but their hybrids with vandas and Arachnis and even Paraphalaenopsis have been more forgiving under my growing conditions.
