Broccoli (Sprouting) Seeds - Summer Purple Broccoli (Sprouting) Seeds \'Summer Purple\' is a British broccoli variety that has been specially bred for summer and autumn cropping seasons. This means that this type of broccoli does not require a winter season of cold weather to be able to grow a mass of delicious spears! The sturdy stems can grow up to 90cm tall and the plants will produce high yields and bumper crops with regular picking. If you decide to sow successionally, you can harvest your broccoli from July to October. The scrumptious dark-purple headed florets taste their best when steamed, with an excellent sweet and earthy flavour coming through. This is a must-have and flavoursome addition to many home-cooked dishes, including stir-fries or Sunday roasts to pot pies and vegetable soups.
