I took a cutting 4 years ago of a cherry tree and finally I see a cherry this year!  I'm very excited about that and am currently waiting for a different cherry to produce as well as gojis.  Trees currently produces fruit are two peaches, two oranges, a lemon, a pomegranate and a fig. 

I also am growing theobromas and avocados that I started from seed, I may have to wait 20 years to see if they ever fruit but it will be worth it! :P
