When the cold sets in, my father brings many of his planters inside to the basement, where he has a special light set up for them. In this way he protects his geraniums, begonias, and other flowers from the elements. It means less of a bill for plants in the spring, and that cuttings can brought up to the dining room throughout the winter.
Here you can see a shot of a begonia bloom that was part of a larger bouquet this weekend,
an abstract shot of the whole bouquet,
and a detail from the vase in which the flowers were arranged.
