Non-Hybrid Onion Plants

Non-hybrid onion plants are open pollinated varieties that will breed true to type, unlike hybrids, which have been developed by interbreeding two or more species. Although many varieties of onion have been improved, or hybridized, over the years, some varieties remain true and will reproduce the same plant from seed time and time again.
