Water gardening has a bit of a history to it, for developing landscapes and aquatic habitats as a leisure amenity the English and the Japanese have quite a few interesting examples to explore

Some links to Japanese water gardens

Some places to Google, for images:
Duke Gardens, Sheffield Park Gardens, Scotney Castle, Burnby gardens, Compton Acres, Imperial Palaces (Japan)

A couple of books which are good on the theme of water gardening:

The Water Garden (Paul, Rees, Guild Publishing- London)

Plants for the Water Garden, Nash Stroupe, Sterling Publishing

Of course, a subscription and all the back copies of the Pondboss magazine is obligatory \:\)

Some quite useful reffies there, to occupy those long, Winter nights with something to mull over
