Allium cepa (aggretatum group)
Days to maturity are from date of transplanting. The sweetest and mildest member of the onion family, important in Asian, Persian and French cuisines.
Culture: Start indoors in Feb. or March and transplant out in spring almost as soon as the ground can be worked. Set 4–6" apart in trenches in well-dug beds with generous quantities of organic matter. Avoid transplanting next to grass strips; slugs love to dine on tiny allium seedlings. Irrigate seedlings whenever the topsoil dries out.
Minimum germination temperature 50°, optimum range 60-70°. We discourage the use of bottom heat because onions germinate poorly in temperatures above 70°.
