Classification of a stem
Herbaceous stems:
They do not have developed ligneous stiffened structures. They are generally frail. We find them in plants like the following:
Annual plants: Plants with a year life-time. Weeds generally belong to this group.
Vivacious plants: Plants with aerial stems lasting a single season, but keeping underground structures from which new stems spring again next seas on.

Ligneous stems:
They have developed rigid, stiffened structures, what we normally know as “wood”. According to the height they attain we classify them into:
| Trees: Plants with ligneous stems, with a superior height of five meters. In this case we call the stems trunks. They do not generally branch up to a considerable distance from the soil. More information about trees / Fruit trees/ How to plant a tree |
|
| Shrubs: Are those plants with ligneous stems, from one to five meters tall. In this case, branching begins at soil level. |
|
| Bushes: Ligneous plants shorter than one meter tall. |
