Calabrese Ironman F1 is a vigorous, dependable variety producing uniform, dome-shaped blue-green heads with excellent flavour. Its high tolerance to common diseases makes it a strong choice for reliable cropping, while closer spacing can be used to produce smaller baby heads. Steam, roast or stir-fry the freshly harvested florets for superb home-grown flavour.
