This document provides an introduction to growing tomatoes, peppers, potatoes, and nightshades in a home vegetable garden. It discusses that tomatoes and peppers are warm season crops best grown from transplants, with tomatoes able to develop roots along their stems and needing staking/pruning, and peppers' heat measured on the Scoville scale. Potatoes are a cool to warm season crop planted as cuttings and usually harvested when foliage dies back after 90 days. All nightshade plants contain low levels of toxins in their green parts that can become more potent when exposed to sunlight.
