When I bought this garden it also came with a pond, (as well as a large shed, a dog run and a small greenhouse, which I'll blog about another time). In spring the pond has suffered from "green soup" syndrome for the last 2 years, which although the frogs and fish don't seem to mind, doesn't look very nice.
Look closely - there's a frog lurking in the rushes
I'm hoping to avoid some of the "green soup" this spring as last year I bought a small waterlily to provide some shade - Nymphaea Walter Pagels. I bought it from Waterside Nursery. I was slightly concerned about buying pond plants by mail order, but as I couldn't find this particular water lily locally I decided to risk it. I needn't have worried as it arrived in perfect condition and even flowered once last year - this year I'm expecting many more blooms.
