Rudolph's large, tasty, superb quality heads can be picked from October-December (from early sowings) right through to January-February (from later sowings in favourable areas). For summer/autumn. Tom says: The slightly untidy cousin of calabrese, broccoli provides you with the first harvests of the year in January-April. The sweet, earthy flavour complements all kinds of dishes from Asian inspired stir-fries to Sunday roasts.
