Also, the average minimum temperature in the UK is much warmer than the average minimums in much of the northern US, while the average maximums in the northern ...
Certain varieties of fig trees are able to survive winter in most parts of Missouri, with a little extra help in the more northern areas. The Celeste fig is hardy in zones 6-10, while the Chicago ...
