It appears that these plants are more tender when young and harden to frost with age. We have two trees growing on a south facing slope here in SW France. We are not in the right area to have a Mediterranean climate, but they have survived a hard frost that cut all the Acacia dealbata to the ground. I don't know the details as this was before we were living here.

We've had one of these growing well in a terracotta pot in our Vancouver, BC (Zone 8) garden for three years. This past winter is survived a week long freeze with temperatures down to -13C. and is now growing well. There is a farm on Pender Island between the BC mainland and Vancouver Island that has a large number of olives but at this point the trees are not mature enough to fruit. The main danger in our climate is exessive winter moisture, but I have read they are hardy to 10F.

There are many varieties, and they differ in terms of water needed - light required etc. It is to my surprise, that ancient trees (like the one in the photo) will produce many very tasty olives if pruned, fertilised and watered. THe plants that are more than 5 - 6 years old will survive a very long dry summer without water, but will produce more and grow bigger if watered, of course.
Nowadays olive trees are propagated with cuttings only. The old locals in Crete believe that seed propagation will res... read more
