A cold hardy lime that I haven't yet killed

I am a notorious citrus tree killer. I admit it. It's not that I'm trying to kill all of them, it just happens. I think I've gone through at least three Meyer Lemon trees and one Kaffir Lime. And possibly a Key Lime. None of them ever flowered or produced any fruit.

Look at them baby limes!

My husband, at this point, is very doubtful of my abilities in citrus. So, last year when I enthusiastically brought home a cold hardy Sudachi Lime that I could plant in the ground and leave outside year round, he was less than excited. He thought I was nuts. I believe there may have been some eye rolling. This was a year ago.

But the lime tree is still alive! And living outside! In the ground! And, lo and behold, it has about 10 baby limes growing on it. He's still doubtful. Granted, the plant is only about two feet tall and they may not survive, but I'm fairly confident this time around that I'll be enjoying some lime based beverage soon. A very small lime based beverage since the fruit only gets about as big as a golf ball. But I'm not picky. I've got limes!

Have you had any success growing citrus - keeping them outdoors in the summer and moving them indoors or just keeping them indoors? Of course, if you live in the south, I'm assuming you have more citrus fruit than you can possibly handle. And, I'm incredibly jealous.
