You want to find a wood that isn\'t allelopathic. I did use pressure treated reclaimed wood- but none of it touches the dirt as I have zinc treated panels on the inside. The wood is also stained and poly sealed.
You are thinking of a solid wood panel? If it isn\'t lined with sheet plastic the wood will rot no matter what you use. Especially if they are deeper than 24\". You will be using a good bit of water in them.
