Mine has been living - in the ground - for 8 years in draughty East Yorkshire and if I didn't keep cutting it back for cooking (and church flower arranging) it would be massive. It's about 7 ft high and 4 - 5 across as it is. I think if they have a good root system they are hardier than you think. It's the potted ones that suffer.
