Southern Giant has mild flavoured, dark green, fringed leaves, making it ideal for both spring or autumn cropping from young leaves or full plant. It produces very tasty greens with mild mustard flavour for use raw in salad or lightly cooked.
Ailsa Craig produces large globe shaped bulbs with a mild flavour beneath golden straw coloured skin. This variety makes for a good exhibition onion but does not store for long periods and should be used in early winter.
EXHIBITION. Mammoth Improved is the perfect exhibition onion because it can be grown to over 2.5kg in weight, and has a lovely uniform shape to the bulb.
