That is an interesting photo. Obviously I've never grown broccoli although I love it, but it's interesting to see the flowers on it.Cher Sunray Gardens
There's not much blooming in the garden at this time of year, Cher, which explains why the bees all flock to the blooming broccoli. In a perfect world, of course, the broccoli wouldn't be blooming. It would have made its way to my kitchen and been consumed before it had time to bolt, but I always manage to miss one or two heads. That's good news for the bees.
I did the same - left town for the weekend, and came back home to find two heads had turned yellow and bloomed. Oh well! At least I was able to harvest 3 other heads last week, before they "bolted" - as you say.
We've enjoyed several tasty heads of broccoli from the garden and few things taste better than broccoli you've raised yourself. But every winter I almost always manage to let a couple of heads "go by," hollasboy. It's okay though. I don't begrudge the bees.
