Woody Vascular Plants
Woody plants fall under two categories: Trees and Shrubs. These categories are largely determined by size. Trees grow to more than 10 m high, while shrubs and small trees are less than 10 m tall. If you do not find the species you are looking for in one category, try the other, or see the list of All Trees and Shrubs at the bottom of this page. Some species may be listed in both categories, like the western yew.
Trees and shrubs are vascular plants — they have well-developed systems of internal tubes which conduct food and water.
