Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about five years even in good conditions, others, usually the larger and more woody ones, may live to 70 or more, but on average they last 7–10 years.

Many trees can grow in multiple stemmed forms also while being tall enough to be trees, such as
