Herbs are the usable parts of herbaceous plants (plants that lack a woody stem). The word herb most often refers to those that have culinary, cosmetic, or medicinal uses. The culinary uses of herbs are what differentiates them from spices.

While herbs are referred to as leafy greens or flowering parts of a plant, fresh or dried, spices, on the other hand, are produced from the other parts of the plants, which are usually dried, including berries, roots, bars, seeds, and fruits.

In general use, herbs are used for food, flavoring, medicine, or fragrances due to their savory and aromatic properties.

Many people new to indoor gardening start by growing an herb garden because they are small and the plants are considered hardy, meaning they can withstand neglect, as well as useful.
