I was very disappointed with my cauliflowers which produced heads the size of a golf ball. 2 of the plants just sat there so I left them in over winter. I was just wondering whether to turf them out to make room for something else when I found they were covered in Purple flower buds - so they've been harvested and the plants left in to keep producing. The PSB plants I knew I had went to seed and/or have not produced much at all - so it was a nice surprise to find I had some after all ,albeit disguised as Caulis. However after yet more batches of unlabelled seedlings [I'm getting quite good at recognising seedling with 2-4 leaves on - but not all of the brassicas] and last years potato ID games - I've gone out and bought labels and a pencil. So maybe no surprises ever again?
