Often bonsai can seem very strict and structured, however, the literal translation of Bonsai is simply planted dish. ‘Bon’ being the dish, and ‘Sai’ modifying that character to be planted. That definition is pretty loose, and bonsai is not as strongly prescriptive an art as sometimes may appear. Trees are judged subjectively on their own merits and character. I’ve always felt that if the tree successfully evokes the idea of a believable (though sometimes fantastical) image of a natural landscape at a small scale, it is a success.
Two pines, in two pots. Both single trees, both somewhere between the informal upright and cascade styles. Not the same though. Neither is ‘better’ in any real sense. Though just for fun compare the two. Which do you prefer?
