I need a greenhouse, too, but where would I put it? lol
That's funny that you got fruits on your kaffir lime - I have never gotten a single blossom on mine! Like you, I only use the leaves, though I would have used the zest in the curry pastes. I don't think that it's one of those things that is going to start flowering after 15 years, though I have seen descriptions of some hardwood trees that don't start flowering until after 20 or 25 years! And a couple of things that I looked into planting, I decided against, after finding that I may have to wait 6-8 years for my first harvest! I can be patient, with some things, but that's a little too long!
