Local greenhouses offer so many differnt gardening ideas. Most houses seperate their yeilds into annuals, perennials, houseplants,etc. Depending on the size of your planter you will easily find Petunia's, Geraniums, Lobelia, Cascading Ivy, Verbenea, or other annual varieties to enhance any window area. Sunflowers however, are not recommended for window boxes.
