茄科, or the nightshade family, is a group of flowering plants known scientifically as Solanaceae. This family includes a variety of important agricultural crops, such as tomatoes, potatoes, and eggplants. Many members of this family are valued for their edible fruits and vegetables, while others are known for their medicinal properties. In addition to food plants, the 茄科 also contains some ornamental species, like petunias and bellflowers. However, it is important to note that some plants in this family, such as deadly nightshade (or belladonna), are toxic and can be harmful if ingested. Overall, the 茄科 plays a significant role in both agriculture and horticulture.
