On June 28th I harvested a broccoli and cut it down low on the stalk. Here's the original plant (if you scrowl down to the June 28th posting you'll find a low-cal soup recipe I made from this vegetable.)
This is how far I cut it down on the stalk.
And less than a month later, this is what I have now.
It's a good example of broccoli regrowth and the prime reason to never yank a broccoli plant after the first harvest. Bon appetit.
