All cane-like and shrub-like begonias develop thick stems. However, there is one group in which the stems are thick from base to tip from the early stages of growth, and these are called thick-stemmed. Some of the plants may grow quite tall, to two metres or more, but most are of medium height, around one metre. They are unusual and are grown mainly by the collector and often used to produce interesting and beautiful hybrids. The following thick-stemmed begonias are examples grown by Melbourne Begonia Society members.
