I have found this tree near my garden's fence early in the year. Then when removing it, decided to plant it in a pot, instead of disposing it to the compost. Later in the summer time, there were very hot days, so the tree had near death experience twice, in other words, it almost die... but then it had revive. Further, I have managed to find a good place for it near were I live. There aren't other big trees that could cast shade on, or to not give to the small tree to "breathe". I can't recall the exact kind of it, but I know that it gives birth to a small green "balls". They were used as a "bullets" in a game with a wooden toy, called "patkalo" - it was able to trow them at great distance.
