Many of our tropical houseplants aren’t so happy indoors during the winter.
Low light levels and low humidity are contrary to their tropical nature. There are some plants in the house, however, that don’t seem to be phased by indoor winter conditions.
If you have moderate light you can maintain a nearly non-stop bloom cycle with African violets. Their fleshy, fuzzy leaves are their defense against lack of humidity; and with adequate sunlight, some fertilizer and well-drained soil you can keep them blooming all year round.
