Tia, wish I was a carpenter, but alas the only skills I have are my imagination and the internet (especially this site, gave me a bunch of ideas).
Since I live in Hawaii, theres a lot of Japanese and Asian influence here so just by driving around I got some ideas for my pond.
As for the plant, yes it's a purple taro plant..they get quite huge and I must admit that it grows like a weed. I read that you shouldn't realease this plant into the wild or else it will infest the waterways. Here in Hawaii, taro is cheap (I got my plant for about 3 dollars) and I have to trim the darn thing once a month or so. I will have to replant the darn plant soon and it's only three months old. As you can tell from the first pictures, it's grown way too big in it's pot and I am actually considering getting rid of it, except that it provides shade for my goldfish...but thanks for the praise.
