[Biology Class Notes] on Herbs and Their Benefits Pdf for EXAM

Herbs are the plants with savoury or aromatic belongings whose leaves or seeds are used for medical purposes, flavouring and garnishing foods, or for fragrances; excluding vegetables and other plants consumed for macronutrients. Herbs are plants containing a lot of uses which includes culinary, medicinal, and in some cases, spiritual. Culinary use typically distinguishes herbs from spices. Generally, herbs refer to the leafy green or flowering parts of a plant either dried or fresh., whereas spices are usually dried and produced from seeds, bark, roots and fruits. Generally, usage of the term “herb” differs between culinary herbs and medicinal herbs; in therapeutic or spiritual use.

Herbaceous Plants – What Are Herbaceous Plants

Herbaceous plants are the plants which can be defined as non-woody vascular stems. The stems reach their full height and produce flowers within one year, before dying back in the winter and then reappearing in the coming spring ready for a repeat performance. In winter, their above-ground growth dies back in the temperate zone, but they may still have underground plants parts like roots, bulbs, etc that survive. Herbaceous plants include grasses – like plants grouped as graminoids, forbes, and ferns. Graminoids are the plants with grass-like appearance, including the true grasses and rushes. Forbs are generally mentioned as herbaceous broad-leafed plants. Banana plants are considered as herbaceous plants because the stem does not contain woody tissue. Technically, every annual plant is herbaceous, because an annual is a non-woody plant.

Herbaceous Perennials

Herbaceous plants are the ones that have an annual, biennial, or perennial life cycle. Annuals take it a step forward and end up entirely at the end of their lone growing season, both above and below the ground. Herbaceous perennials and biennial plants may have stems that die at the end of their growing season but still may leave parts of the plants which survive from season to season. 

As we read from the above discussion that herbaceous plants reappear in the springtime. The term ‘perennial’ essentially means that the plant will live for more than two years.
