An heirloom sweet yellow onion (Allium cepa) that originates from the Bermuda Islands by way of Texas (for more history, see “The Onion That Came To Texas But Never Left The Same”). Early Grano is a short day onion requiring a day length of 10-12 hours in order to initiate bulbing. These onions perform best in warmer, Southern climates, but this one’s got a little bit of latitude to travel north.
75 days spring sown, 110 in fall plantings. Biennial.
