Blood Oranges.Anyone grow them in containers?
 

I have a real fondness for Blood Oranges.They are only available for a short time at the local market.Wish I could get down to California and buy a box when they are in season.

What kind of a challenge are they to grow in a container?Our local climate can dip into the teens in the winter,and that is just too cold.

Any input on varieties to grow would be helpful.
