Nightshade plants refer to a group of plants that belong to the family Solanaceae. They are called "nightshade" because some of these plants bloom at night. Examples include tomatoes, potatoes, peppers, and eggplants. However, the term
"nightshade plants" is often used to refer specifically to a few poisonous plants in the same family, such as deadly nightshade and belladonna. These poisonous
nightshade plants contain toxic substances that can be harmful if ingested.
