@ctrl-alt-nwo, That's pretty interesting gardening post. with valuable information. Topiaries are plants pruned or shaped into certain forms. These forms can be as simple as a pyramid or as complicated as a giraffe, elephant or other animal shape. Sometimes topiaries are created out of the plant alone, or they are created as a result of training a plant over a frame. The best plants to choose for a stand-alone topiary are those with small, dense foliage. Those that are trained over a frame should be vining and have dense foliage that will quickly fill in any empty spots and form a dense mat.
I send this video how to maintain this plant.
