Answer: Sunflowers probably require more light than you can provide indoors during winter. Their bloom coincides with specific day lengths - something that would be hard for you to calculate and duplicate indoors. Why not try to grow something else instead? Mosthouseplants bloom in the summer, but Solanum capsicastrum (Winter Cherry) blooms in the fall and develops bright red fruits in the winter. You can also force crocus and daffodil bulbs so they bloom in winter. Either of these choices will bring color intoyour home during the dark days of winter.
