Depends how big the area is and whether you're planning a bog garden - select B at the bottom of the page and then select bog plants.

cool thanks. area`s petty big and in a river flood zone =)

In that case, as long as its more than 45 feet minimum away from any house (specially yours) put some willows in, the coloured bark kinds that need stooling every year - they like a lot of wet and will suck quite a lot of it up.
