Seed varieties refer to the different types of seeds that can be planted to grow specific plants. Each variety has unique characteristics, such as size, color, and growth habits, which can affect the plant's yield and resilience. Farmers and gardeners choose seed varieties based on their climate, soil type, and the specific crops they want to grow. There are two main categories of seed varieties: heirloom and hybrid. Heirloom seeds are open-pollinated and have been passed down through generations, often prized for their flavor and adaptability. Hybrid seeds, on the other hand, are created by crossbreeding different plant varieties to produce seeds with desirable traits, such as disease resistance or higher yields.
