Japanese Fantail Pussy Willow

I had seen these last week at the Home and Garden show, but resisted because of what I had heard about growing willows. When my fellow booth mate brought back the coveted gnarly willow and the black one I had to pick her brain about it! She said it was just the curly willow so I bought a bunch of the gnarly looking one, but what I have read online said any water loving plant is an issue. So I dunno....what do I do now? Where do I plant it? It is rooting in a bucket of water now.
