Somebody thought that adding a flowering tree in a pot would enhance the ambience at the Imperial City in Hue (see Imperial City). And then several years went by and they forgot about the little tree. And it got pot bound, and then turned into a bonsai specimen with a lovely, yet labored architecture. And one small pink flower. For me, indeed a significant enhancement to the weathered yellow and red building behind it. [NOTE: I may have been the only visitor that day who paused, reflected, and took a photo of this tree].
