We had some days in December where the night time low was in the twenties and the high in the upper 40s. I have been wintering some plants outside for the first time and these Laelias suffered cold damage. The hardest hit were the Laelia purpurata.
Laelia purpurata grows in Brazil and needs a dry winter rest. It is fragrant, cool to hot growing and needs bright light. It can bloom any time from late spring into fall.
At the time of the cold nights the plants were quite dry. They had not been watered for at least a month but had had some dew, so the sphagnum surface was not rock hard. There was immediate blackening of the leaves. I moved the five plants to Sonoma where they could be inside the greenhouse. This is the only one of the five that looks now like it is not just damaged but is dead.
Next winter I will try again. I will have electricity so I can have a string of lights and some plastic around the plants to raise the temperature a bit.
