Where I live, these are very common in fact they are almost every where, trust me, by time it will be hard to get rid of them, then trying to cultivate them. Technically if you just trow it on the ground as a leaf it will grow, (every prickle is an opening for a root). But any way good luck and don't forget to cut some of the leaves (when it grows into a tree) to let it grow higher instead of taking the ground.
