I have heard this is common for Romanesco to grow so well and tall, i.e over 3 feet, maybe even 4 feet, and most people say Patience is required, the heads suddenly appear.

Well its now 3rd week of October, frosts will start anyday now and I see no heads at all, although the central top leaves have started twisting over each other. I have NO Experience of this vegetable and wonder if I should just dig them up and try again next year? Maybe we can eat the top central leaves like cabbage???. Brussle Sprouts (Bedford) also show similir effects but at least they have developed some Sprouts............ANY IDEAS????

Try shopping your seeds where you can se how fast the varieties are. Don´t know if you speak swedish or have friends that speak swedish but these swedish mailorderfirms do print in there catalogue how many days of developing time the vgetables have and they do deliver to finland.
