Anyone? It was terrible, one of the worst things I tried out of my garden. It has been about 10 days and others are not at all white and look the same as before I tied leaves up.

Too much heat so it started to bolt and turns bitter. Cauliflower is very plant age and air temperature sensitive when it comes triggering bolting. Some varieties more than others. Plant out time and age of the transplant when transplanted can be crucial. It works much better for many as a fall crop when the weather is more cooperative.

I have ahd bolted stuff and this did not seem like that. Buds were all still tight and 1-2% looked like they just started to flower (within 24 hours). Not disagreeing jsut did not seem like it - other plants still ok 1 week later. Also the odd green color.....

Is it Romanesco? Mine are huge plants, with deformed heads, tastes ok though.

There's an heirloom variety of cauliflower called Green Macerata that I grow--huge plant & very tasty. Your plant looks similar.
