Answer: Heirloom seed are open pollinated varieties that you can save the seeds from year to year and get the same variety each year. Hybrids are varieties that have increased growing vigor, pest resistance and production than the open pollinated types, but the seed cannot be saved each year and you'll have to buy new seed each spring. Heirlooms have many characteristics gardeners like (unusual colors, tastes, shapes...), while hybrids are generally higher in yield, more widely adapted and more consistent in producing. Try a bit of each and you decide what's best for your tastes.
