I have to agree with Craig, that grass in a pot, may be beautiful, and to me is a 'landscape planting' but it isnt a 'bonsai' IMO. A bonsai is a tree or trees in a pot without stuck on stones, bridges, houses, horses mudmen cars etc etc. just the tree or group in a pot. Simple. I have seen some wonderful pictures (in a chinese book i think) of horses grazing on hills beneath wind blown trees, but i wouldnt call it bonsai, its a landscape planting. It was beautiful.
When you paint a house, it that a work of art? (well it isnt when i do it
) but it is painting, its just a different form of the same thing, no better no worse, but not the same. maybe a bad example but im sure you get what im tring to say...
