What do you get when you cross a sheep dog with a bunch of daffodils? A collie flower!

Brassica oleracea botrytis is a group of plants that we commonly refer to as cauliflower. Native to Western Europe, it doesn’t like temperatures that get too hot. However, it does thrive best in a full sunlight position. It does take a little skill to successfully cultivate, but being able to consume a vegetable that you grew yourself more than makes up for the extra effort.
