Shop Onions by Day Length
Onions are a biennial vegetable grown commonly as an annual. While the seeds can
be harvested in the second year. Onions themselves are commonly harvested in the first year for the
vegetable. We offer a variety of bulbing onions which you can browse by type: Short day onions, are ideal for the southern states, intermediate day onions do well throughout the
United States, and long day onions are best for northern
latitudes. We also offer a great selection of bunching
onions.
