What advantages do they have over hybrids?
Flavor, flavor, flavor! One of the first reasons people grow open-pollinated or heirloom seeds is the flavor. Hybrids are bred for many characteristics such as uniformity (in shape or harvest time), high yields, withstanding rigors of transport, etc. But, sadly in the breeding process the desirable characteristics like flavor and nutritional value suffer. There’s truly nothing as delicious as a sun-ripened home-grown heirloom tomato. You tomato lovers out there know just what I mean when I say we suffer each winter, waiting for the first delicious tomatoes of the next garden season. 🙂
