Piracicaba Broccoli (also sometimes called "Broccolini")
I have found that Piracicaba Broccoli works much better for our climate. Harvest some looser, smaller heads, and lots of side shoots and leaves instead of waiting for a big head.
Here's a link to a story about it from the Washington Post http://www.washingtonpost.com/wp-dyn/content/article/2006/10/18/AR2006101800375.html We have it for sale for the next 3 weeks or more and it's a good time to plant it now (the sooner the better, as it prefers cold weather)
We will also have Broccoli Rapini, Collard greens, Bok Choy, 9 types of Kale, Mustard Greens, Onion starts and all the cool weather plants that we usually offer ...
