10 Nightshade Vegetables Perfect For Your Garden

When you think of the nightshade family, your mind may go to the highly poisonous plants that you're wary about planting in your garden. Likely, you're already familiar with water hemlock, foxglove, and wolfsbane. But what about the nightshade vegetables that are growing in your backyard right now? That's right; your favorite garden-grown fruits and vegetables like potatoes, tomatoes, and eggplant are just as toxic as the ominous deadly nightshade.

Still, that doesn't mean that you shouldn't nurture delicious, home-grown produce, such as tomatillos, pepinos, and cayenne peppers. As long as you know which parts of the plants to avoid, you can be well on your way to making a wonderful organic meal. Some nightshade vegetables are reported to be hard on the stomach and problematic for people with autoimmune diseases or irritable bowel syndrome, as noted by Healthline.

Yet for others, they are a great source of vitamins, antioxidants, or fiber. It's important to understand the risks that come along with consuming products of the nightshade family before choosing one or more of these 10 plants to grow in your own garden.
