Frost-tolerant vegetables are plants that can withstand cold temperatures and light frosts without significant damage. These vegetables often thrive in cooler weather, making them ideal for early spring and late fall planting. Common examples include kale, spinach, and broccoli, which can continue to grow even after a frost. These vegetables have developed adaptations that allow them to survive in chilly conditions. For instance, they may have thicker leaves or higher sugar content, which helps prevent cell damage from freezing. Gardeners often choose frost-tolerant varieties to extend their growing season and enjoy fresh produce year-round.
