What are nightshades

Solanaceae plants are a family found within the angiosperms . These, in general, are usually either herbaceous or shrubby. Grouped in approximately 95 genera, more than 2,500 different species of this very particular family have been discovered . In addition, Solanaceae have a wide distribution, both in tropical and warm regions as well as in temperate and cold regions. However, most are grouped in the American continent and a few others in the area of ​​Eurasia, Africa and Australia.

These plants, due to their wide variety, can be annual, biennial or perennial. Another common trait is that they tend to have mostly underground tubers . However, the most characteristic part of this family is its high content of its own alkaloids that are harmful to health if they are at high levels.

However, the vast majority of nightshades are used for their multiple uses, some even pharmaceuticals. The economic importance of these plants worldwide is triggered when we think of eliminating foods such as potatoes, tomatoes or peppers from our diet. And in the same way, in some cases, stop producing cigarettes despite the contraindications to their consumption, since the tobacco plant is another belonging to this family.

Finally, we also want to highlight some plants of this family that, despite not having these striking fruits, are highly valued for their beauty, such as petunias. And it is that all Solanaceae offer a gift in sight in their flowering season. So for all this, whether when you see them in your garden, your garden or inside your home, remember the importance of this family that lives with you in your day-to-day life.

Solanaceae characteristics

These are the main characteristics of nightshade plants :

  • The leaves of most nightshade plants are simple and arranged alternately on the stem. In addition, they usually have lobed margins and in many cases with spines.
  • Solanaceae are hermaphrodite plants that present both actinomorphic and zygomorphic flowers, which are generally arranged solitary in some specific species in the form of inflorescences , both axillary and terminal. The shape of these is usually campanulate.
  • As for its fruits, they are usually berries or drupes .
  • The seeds are dicotyledonous with a straight or curved embryo. Furthermore, in most of the species belonging to this family they are polyploid.
  • Its chemical composition includes alkaloids, such as atropine, hyoscyamine or nicotine, common in many toxic species within the Solanaceae family.
  • Solanaceae also contain other substances, such as capsaicin, an oleoresin that usually causes a mild irritating effect and has a spicy taste, as in the case of chili.
  • Finally, they have solanine. This toxic and bitter-tasting glycoalkaloid is found naturally in the leaves, fruits, and tubers of some edible nightshades. Hence, it is not advisable to eat these vegetables if we see that after removing the skin, the remaining layer is greenish. It can cause stomach problems and other serious symptoms to our body.
