Thanks, guys! Do you think a cutting from this could be grafted onto a lychee or orange tree? Or really, any other variety of fruit tree?
Don't think so, but this is a vigorous, fast growing tree that can get huge in no time from seed. A friend of mine had a tree in Cuba (we call it mamoncillo or mamon) and as far as I can remember, it needs to get to a certain size to start bearing fruits and once it fruited, the only way to collect the fruit was by climbing the tree —which is not advisable for the average guy in the U.S. for the following reasons:
1. Climbing trees is something you have to learn as a kid and for that, you were NOT supposed to be a spoiled-stay-home-playing-games-all-day type of kid, you were supposed to be a barefoot street kid, full of scratches and broken bones.
2. If you think you learned with the Boy Scouts how to climb a tree, by now you're most likely fat and heavy and you need to get to the tip of the branches, so you'll break the branches and fall down.
3. If you decide to climb the tree anyway and you fall down, you'll most likely get sued by someone, don't know, but someone will sue you, your wife, your kids, your city, even yourself, so don't go broke for a Spanish Lime tree, it's not worth it.
BTW, I recently got some from my Puerto Rican friend and over there they call it "quenepa"
