Herbaceous plant

[5] Some orchids, such as species of Phalaenopsis, are described in some sources (including the authoritative Plants of the World Online) as "herbs" but with "leaves persistent or sometimes deciduous".

Some habitats, like grasslands and prairies and savannas,[17] are dominated by herbaceous plants along with aquatic environments like ponds, streams and lakes.

The age of some herbaceous perennial plants can be determined by herbchronology, the analysis of annual growth rings in the secondary root xylem.

For example, if you frequently and shortly cut the grass without watering in an arid zone, then desertification occurs.

[citation needed] New growth can also develop from living tissues remaining on or under the ground, including roots, a caudex (a thickened portion of the stem at ground level) or various types of underground stems, such as bulbs, corms, stolons, rhizomes and tubers.
