The yaupon holly, also known as cassena, is an evergreen bush that has an irregular branch pattern and small oval leaves.
An interesting fact about this tree is that although parts of the tree are poisonous, especially the berries, the Seminoles have made tea from the leaves. The leaves of the yaupon holly have a high caffeine concentration. The tea occasionally caused vomiting giving it the scientific name vomitoria.
It takes pruning and shaping well which is a good characteristic for a bonsai tree to have. This outdoor bonsai grows in USDA zones 7a-10b and is a Florida native.
