Full-Size Onions

Onions get their cue to start bulbing up once days reach a certain length. To grow onion plants that form robust, flavorful, full-size bulbs by the desired harvest time, it is important to choose varieties best adapted to the pattern of day length in your region. Johnny's line of full-size onions have been bred, trialed, and selected for adaptation to the three major latitudinal windows: long-day, intermediate-day, and short-day.

Use our Full-Size Onion Comparison Chart to select the best varieties for your region, and to compare bulb size, color, shape, adaptability, storage potential, and other distinguishing characteristics.


Johnnys is committed to your success and is with you every step of the way.
