So you want to turn an ordinary green garden into a showplace? You may need the right ornaments like sculptures, statues, metal lanterns, wall pieces, earthen urns and maybe an occasional topiary tree. If you've seen Tim Burton's Edward Scissorhands you are familiar with topiary trees, as they were used as part of the set for the classic film. Topiary tree designs can act as powerful symbols for your garden, giving it a character. Topiary trees are also relatively easy to make.
