Small Water Gardens are great for a few of reasons. They look great, sound lovely (with a small fountain), relatively inexpensive, easier to maintain than a large pond, and you can have them in a small area such as a patio or balcony.
They're foolproof too. If you wind up with a design that you don't like, it's easy to rearrange the plants. Small-container water gardens are actually a collection of submerged potted plants, so redesigning a planting is as simple as moving the pots around. And the plants are tough -- most are hard to kill and require virtually no maintenance. All you need is a sunny spot with at least six hours of direct sun a day, something that holds water, and a few plants. For me, small-container water gardens have been an endless source of inspiration. And once you've mastered a small container, think what you can do in a big water garden.
