I've had mine for over 5 years, first in the ground for 2 years, nothing was happening. I then put it in a wine barrel container, that's the last 3 years, put out more branches, healthy looking leaves, not a single flower or fruit. It has been mostly in partial sun. I must say that neither cold (30 F) nor hot (105 F) bothers it. I'm planning on moving it into full sun in the spring, hopefully I"ll get it to fruit.
