Contraindications & WarningsConsumption of green potatoes, sprouts, or the leaves and stems of the potato plant is toxic due to high levels of glycoalkaloids (e.g., solanine), which can cause nausea, vomiting, diarrhea, headaches, and neurological symptoms. Only properly stored and prepared tubers should be consumed. Individuals with allergies to the nightshade family should exercise caution.
Cultivation NotesPotatoes are typically grown from seed potatoes (pieces of tuber with 'eyes'). They require full sun, consistent moisture, and fertile, well-drained soil. Hilling (mounding soil around the growing plant) is essential to protect developing tubers from sunlight, which prevents greening and the formation of toxic solanine.
Raritycommon
