Long day onions require 14 to 16 hours of daylight to form bulbs. As a result, they perform best in northern latitudes where the summer days are long. We offer a complete selection of long day onion plant varieties that includes red, white, and yellow onions. If you want to grow more than one variety, try our Long Day Onion Plant collection which includes a red, white, and yellow variety.
