Niwaki means garden tree. Not very exciting, but it implies far more than that. Japanese gardens are landscapes, microcosms of nature, and the trees are all shaped to fit into those landscapes - there's an awful lot of artistry and cultural baggage in there too. Jake's written a book on it all, if you're interested. So, the name. Hard to pronounce (ni-whacky) and tricky to remember, but we like it because of its implications.
