I bought a apparently Romanesco Zucchini this year...usually I grow my own from seed but I didn't do a seed order this year and I couldn't find the seeds in the store. These plants are strongly vining and don't look like zucchini to me. They looked like it when they were small but I'm sure I have some sort of winter squash. I don't have room for them where I planted them - can I transplant them? They are about 12 -16" now and growing madly.
