Some plant species used to create Bonsai are considered classic. Those include Junipers, Maples and Pines. Other suitable species of plants include Birch, Beech, Elm, Ginkgo, Hornbeam, Cedar and Yew. As a side note, Larch also makes a good Bonsai, but has a tendency to shed branches for no apparent reason.
