WINTER COLOR
There are a lot more options for adding winter interest to your pots than the standard pansies and ornamental kale and cabbage.
Pansies are still the best to plant over tulips and narcissus as the bulbs can easily grow up through the roots. There are lots of colors and types including some very nice, small-flowered violas. The breeders come out with new ones every year. Cabbage and kale will look good through late winter, but will begin to "bolt" as the light increases.
