I have a fondness for plants from Crete. It amazes me that they can be so cold hardy. I can only assume it has something to do with the ice ages some 10000yrs ago (or whenever) which must have made Crete a much colder island. Those plants still have that hardiness locked up in their genes. Dennis in Cincinnati, Ohio (USDA Zone 6)
