Description

Unripe cauliflower: raw or cooked. In early spring, the plant forms a small cauliflower, which is followed by 6 to 12 smaller cauliflowers on side shoots during the harvest season. Although the plants are not very productive, they have a good flavor and are an excellent vegetable. Leaves: raw or cooked. They have a mild cabbage taste and can be harvested throughout the year. However, be aware that excessive harvesting can weaken the plant, which may reduce the yield of the flowering heads.

Harvest starts: 01/06
