Any substantial plant can be trained into a bonsai if it can adapt to the shallow pots and restricted growth that bonsai require. Most bonsai are hardy outdoor plants that need a period of cold dormancy in the winter to thrive, but they should be protected from the harshest winter conditions. Some of the most popular species have remained so for centuries among bonsai enthusiasts. They offer special features such as flowers, attractive bark, small foliage or seasonal fruits and cones. They include the following plants:
Azalea (Rhododendron) These are easily trained into tree form and can be used for most styles. In late spring, they produce spectacular flowers. Several flower colors are available.
Beech (Fagus) - Deciduous beeches tend to be grown in informal bonsai styles. They require very special and delicate technique in styling.
Fig (Ficus) - This tropical family includes some species that have been trained to grow as indoor bonsai. Still, these plants should be placed outside when the weather allows.
Juniper (Juniperus) - Probably the easiest genus for a beginner, evergreen juniper is readily available and can be trained in most styles.
Maple (Acer) - Two main species of maple are used in bonsai: Japanese maple (Acer palmatum) and trident maple
Bonsai are shaped by pruning, wiring and pinching. Pruning and wiring create the tree’s structure by shaping its woody parts, whereas pinching back the long ends of soft foliage helps side buds to develop, making a branch bushier or twiggier
(Acer buergerianum). These deciduous plants are easy to care for, and many display stunning fall colors.
Pine (Pinus) Pines make beautiful bonsai, but are not ideal for a first tree because they are difficult to train.
Pemphis acidula Pemphis make oneof-a-kind bonsai, but are not ideal since collection of the material from the wild is very difficult and expensive.
Bonsai Plant Guide
Trees and shrubs are suitable for traditional bonsai. Specialty nurseries often have a wide selection of dwarf and semi-dwarf varieties of many species. Dwarf plants, however, do not always convey the same impression as their full size counterparts because their growth habits are quite different. Some trees and shrubs that work well as bonsai are azalea, beech, boxwood, ginkgo, maple, oak, pine, wisteria, and zelkova.
