Romanesco are a very pretty intense bright green. They are in the broccoli family so they taste kind of like broccoli. I'm not sure how big they are supposed to get but I think mine are on the small size. The plants got hugh! Bigger than my cauliflower. They also seemed to take longer to grow. But here they are a great winter crop. They also have small bublets under the main head. Maybe these would grow into another head but I was impatient to pull them out and get the bed ready for my spring planting which is around the corner.
They just take up to much valuable space for me to grow them again. I will stick to growing cauliflower which matures faster and is a smaller plant. I've only grown the white one but come fall I will grow the white, green, and purple ones. The green cauliflower is the same green as the romanesco.
