Oh, cloves are USDA zones 11-12. I didn't realize they were tropical. At any ratez we have successfully groqn turmeric here. Bring it inside below 20°C, put it in the shade over 30°C, and put it in the sun if it's in between. It's a bit of work, but it's a tried and true technique. So I think the process would be the same for growing cloves.
