This very attractive, unusual, bright lemon till yellow green rosettes have a very delicious, somewhat nut-like flavour. This variety can be harvested from august till december, when there's a mild frost. Steam this variety or eat it raw and then the form and colour will stay the same.

Cauliflower needs a lot of exta manure. You also need to water them profusely, especially during droughts. Give once a week extra water around the plant and not on the plant. To prevent the cabbage fly from laying it's eggs on the foot of the plant, cover the plants with a cauliflower collar. The young larvaes eat the roots of the plans. Snails and slugs can also be a problem to cauliflower. Harvest the cauliflower by cutting the stem with a knife and remove the cabbage carefully. You can keep cauliflower approx. 7 - 10 days in the cripser compartment of your fridge. You can also divide the cauliflower in rosettes and freeze them.
