One of the dangers in walking the street is I might see a pretty tree. And take some seeds. And plant them. And then – wham! – it’s two years later I’m watering a couple dozen seedlings with no idea what to do with them.
As best I can tell, this is a Judas Tree – lavish pink flowers, heart shaped leaves, and smooth grey bark. This is bonsai-able, although to be honest I only checked that later.
I’m guessing at how to germinate, but it’s not all that hard.
