Answer: Foxgloves are biennials and make a rosette of foliage the first year followed by blooms the second. By planting seed in early summer you would mimic the plant's natural cycle and should have blooms the following year. One variety of Foxglove called "Foxy" grows quickly and can sometimes flower the first year if started very early indoors so it might conceivably flower next year if planted in the late summer or early fall. Planting in fall, however, is more often used for plants such as annual poppies and larkspur. I would plant the seed early next spring, but you could always experiment and see which works better in your garden.
