With winter arriving and the holiday season upon us, gardening thoughts turn indoors to houseplants and decorating. This year, I saw poinsettia plants for sale at the big box stores on the first of November! That is really pushing the season, in my humble opinion. Many gardeners purchase poinsettias for the holiday season, and I have written about these plants in past columns. The poinsettia is the number-one flowering potted plant sold in the USA.
