Purple cauliflower

Wikipedia - The purple color in this cauliflower is caused by the presence of the antioxidant group anthocyanins, which can also be found in red cabbage and red wine.^[17] Varieties include 'Graffiti' and 'Purple Cape'.

In Great Britain and southern Italy, a broccoli with tiny flower buds is sold as a vegetable under the name "purple cauliflower"; it is not the same as standard cauliflower with a purple curd.
