Maintaining a colorful flower garden can be challenging during the winter and, in some places, nearly impossible to do outdoors. However, you can still find ways to surround yourself with flowers during the bleaker months of the year, wherever you live. In warmer climates, you may be able to grow flowering plants outdoors in the winter. During milder years, flowering plants may also bloom earlier in the spring or later in the fall. If you live in a cooler climate but want some outdoor color, consider planting blooming trees, shrubs or even "weeds." While winter-blooming flowers may be less colorful than summer-flowering species, they can still add interest to your landscaping. In cooler climates, the easiest way to grow flowers in the winter is to tend to them indoors. Another option for indoor gardening is to force bulbs to bloom indoors, coaxing beautiful and exotic varieties to blossom in the dead of winter.
