Herbaceous plants do not produce perennializing above-ground structures using lignin, which is a complex phenolic polymer deposited in the secondary cell wall of all vascular plants. The development of lignin during vascular plant evolution provided mechanical strength, rigidity, and hydrophobicity to secondary cell walls creating a woody stem ...
The word herbaceous is derived from Latin herbāceus meaning "grassy", from herba "grass, herb". [9] Another sense of the term herb can refer to a much larger range of plants, [10] with culinary, therapeutic or other uses. [6]
Deciduous perennials include herbaceous and woody plants; herbaceous plants have stems that lack hard, fibrous growth, while woody plants have stems with buds that survive above ground during dormancy. [15] Some perennials are semi-deciduous, meaning they lose some of their leaves in either winter or summer. [16]
A prefix meaning "two", e.g. bisulcate, having two sulci or grooves. biennial A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid
Each plant commences its growth as a herbaceous plant. Plants that remain herbaceous are shorter and seasonal, dying back at the end of their growth season. Woody plants (such as trees, shrubs and woody vines will gradually acquire woody (lignaceous) tissues, which provide strength and protection for the vascular system, [4] and they tend to be ...
A herbaceous border is a collection of perennial herbaceous plants (plants that live for more than two years and are soft-stemmed and non-woody) arranged closely together, usually to create a dramatic effect through colour, shape or large scale. The term herbaceous border is mostly in use in the United Kingdom and the Commonwealth.

A forb or phorb is a herbaceous flowering plant that is not a graminoid (grass, sedge, or rush). The term is used in botany and in vegetation ecology especially in relation to grasslands [1] and understory. [2] Typically, these are eudicots without woody stems.
