This variety of bunching onion seed is open pollinated meaning that the saved seed will reproduce the same plant that the seed was from. Since onions are biannual, they need 2 seasons to produce seed, so these were planted from seed last early summer and will go to seed next early summer. I can then harvest the seed. I do this every year to make sure that I always have seed. If I end up with more seed than I can plant, the seed is sprouted and used in salads!
