Types of cauliflower: purple, green & white varieties
In addition to the classic white cauliflower, coloured cauliflower varieties are becoming increasingly trendy for growing in your own garden. It is important to consider the growing needs when choosing a variety.
The many varieties of cauliflower (Brassica oleracea var. botrytis) differ mostly in taste, colour, and harvest time. Of course, to start growing cauliflower, you must first choose one of the many varieties. Read on to find out about the different types of cauliflower and how they differ.
Types of cauliflower: how many are there?
It is impossible to give an exact number here. However, as the cauliflower has been bred for centuries, it is reasonable to assume that there are hundreds of different types and varieties of cauliflower. Generally, a distinction is made between white and coloured varieties.
- White cauliflower varieties: These varieties are among the most widely sold and grown in the UK, both in private gardens and in commercial cultivation.
- Coloured cauliflower varieties: Yellow, green, and purple cauliflowers are more nutritionally valuable than their white counterpart due to a higher concentration of vitamins and other elements, and they look quite pretty too. The colouring of these varieties is caused by exposure to sunlight, which causes pigments such as beta-carotene to develop in the cauliflower. If the cauliflower is green, it does not indicate that it is not yet ripe. Colourful types of cauliflower, by the way, have a more intense flavour than white cauliflowers.
Tip: Even white cauliflowers do not stay completely white under strong sunlight. Cover these varieties to prevent cauliflower sunburn.
