It can be so dreary, dark, gray, cold here in the Pacific Northwest in winter. You get occasional days of sun. But so often it is depressing. The current temperature is 'warm' - 45°F or 7°C. Today it is a steady beat of a light rain. I have to turn on the lights in the afternoon. The warm glow of a candle can give a cozy feeling but otherwise it is just damp and cold.
But one thing that does add joy and warmth to the winter are orchids. Many of the species bloom in the winter and their blooms can bring joy to a room. Our local supermarket has had many on sale for around $10 - $12 US. That is almost less than a bouquet of flowers - and they last much longer.
We have a greenhouse which helps to grow them but in the winter once they have come into bud or we purchase them, we move them into the house. The cooler species such as Oncidiums, Miltassia - we can have in the living room. Others that take a little bit more humidity such Paphiopedilum and Phalaenopsis, we keep up in the bathroom. It has a skylight and high humidity and they bloom throughout the winter months. Their beauty brings us joy on the gray days.
