Very thick stems for autumn harvest. Named varieties include Snowstar and Jolant. Good all-rounder.
Flavour
Autumn Mammoth offers a mild, sweet onion flavour with subtle earthy undertones, making it less sharp than spring leeks.
In the kitchen
Its thick stems hold up well to direct heat, making it ideal for grilling or slow roasting over coals where it caramelises beautifully without falling apart.
Growing
Prefers deep, fertile soil with consistent moisture; best grown with ample spacing to accommodate its large stem size and to prevent overcrowding.
