Broccoli is one of those vegetables that we tell our kids are good for them and as a result they refuse to eat it. But that is no reason to stop us growing this useful vegetable. In fact what we are concerned with here is the broccoli cauliflower cross known as Broccoflower and the Romanesco broccoli. I found an article on the Gardening Channel which has instructions on how to grow these vegetables and how to deal with common problems that can occur.

types of broccoflower and how to grow
Two similar vegetables are sometimes called broccoflower. One is a trade-marked hybrid between broccoli and cauliflower, richer in vitamin A than either of its parents and also well endowed with vitamin C. Its cauliflower-shaped yellow-green heads have a sweet cauliflower-like taste.
The other is also called Romanesco broccoli. Its lime-green heads with conical florets may weigh up to 4-5 pounds at maturity. Care for the two vegetables is similar, but Romanesco is slower to mature and can grow larger. You can harvest cauliflower-type broccoflower 70 days after transplanting, but Romanesco requires nearly 100 days. Romanesco is an Italian heirloom with a nutty flavor and is a popular vegetable in fine restaurants.

How to Grow and Care for Broccoflower

Broccoflower is a cool-season crop. Northern gardeners should transplant 4-6 week-old broccoflower seedlings outside 2 weeks before the spring free-frost date (your local Cooperative Extension can tell you when that is). Southern growers may set transplants out in August for a fall harvest or (in very warm areas) plant seeds in October for a winter harvest.
Broccoflower thrives in a very rich soil with lots of nitrogen. Add several inches of finished compost or well-rotted manure to your soil before planting. You can mix in a small amount of blood meal for an extra nitrogen boost.
Mulching your broccoflower with lawn clippings (from a lawn that?s not treated with herbicides) will help to keep the soil cool and weed-free as well as providing an extra nitrogen boost when the clippings break down. Biweekly feeding with compost tea or fish emulsion will help your broccoflower to thrive.
