Broccoli Romanesco
Romanesco looks a little like a cactus, with tight clusters of bright-green cone-shaped heads. The taste is said to be milder than regular broccoli, with a delicious nuttiness. Also called Romanesque cauliflower, this veggie is a cool season crop that will bolt in the summer heat—gardeners in climates with hot summers should plant in late summer to early fall for best results.
