Here is the arbor I am trying to replicate in my yard. I will post pictures once it is done so eveyone can compare my end results to the one at the garden show. the wood they used was Hedge Apple. It is also known around here as Osage Orange. It is a very durable and long lasting wood. Needless to say I do not have any Hedge Apple wood but do have a lot of misc. wood that I will use. I know it will not last as long but I will have the same effect for a few years. If I seal it that might make it last a few more years.
