In Mediterranean-like and warmer climates, you can grow it and keep it outdoors in winter.

When outdoors, remember it can hold to temperatures as low as 17°F (-8°C).
What is best is to use horticultural fleece which will let it cope with these low freezing temperatures best.

If you are growing it in a pot, the best thing to do is to move it to a greenhouse or an unheated lean-in so as to protect it from freezing, while letting it feel the cool it needs over its winter dormancy.
