Solanaceous Plants: Care And Harvesting Tips For The Most Popular Varieties.


The nightshade family is large. It includes beautiful ornamental plants as well as some of our most popular vegetables.

What are nightshade plants
Nightshade is the name of a plant family that includes about 100 genera and nearly 3000 species. You can often recognize nightshade plants by their flowers: they are cup-shaped and usually have five leaves. Their seeds ripen in the ovary of the carpel – they are angiosperms. The seeds eventually ripen into fruits, which have a permanent place in our everyday lives.

The plant family probably got its name in the Middle Ages. Even then, various nightshade plants were used as medicine, for example for better sleep. However, since many nightshade plants are poisonous, they were also considered witch herbs at that time.

Cultivated nightshade plants do not contain any dangerous toxins. The versatile plants enrich our menu and gardens.
