Deciduous Bonsai Species
Bonsai and Tree Species that lose their leaves go dormant during the Winter months.
The Rhododendron genus is massive and includes anything between 500-900 species depending on which authority you consider. Some species are so similar to others that they are listed as subspecies rather than distinct species in their own right, others are established hybrids (such as Kurume and Satsuki) that are sometimes regarded as species in their own right.
Acer palmatum are deciduous small trees and shrubs, with opposing odd-numbered (anything from 5-11) pointed leaves, native to Japan, China and Korea. There are at present hundreds of varieties in cultivation. They are very popular for use as bonsai due to their ready ability to respond to most bonsai techniques, beautiful foliage and graceful branch structure.
