How Has This Romanesco Broccoli Not Bolted? 

I’ve been on a quest to grow Romanesco broccoli for the last two summers and it hasn’t quite worked out. I haven’t been able to find a good growing window for this cool-season crop. At least I thought it was a cool-season crop. 

Last week we had multiple days of 90 degree weather, but this plant just keeps getting bigger and bigger. No broccoli, no flowers, but an enormous plant. Is it possible that it hasn’t bolted yet, even in this heat? 

If it has bolted, I want to get it out of the garden, as it’s starting to shade some of my other crops. What do you think? Keep it or pull it up?
