Squash varieties are grouped as summer or winter types, depending on days to maturity and harvest periods. As the names suggest, summer squashes mature for fresh eating in the summer, while winter squashes can be stored for eating well into the winter months. Easy to grow and often prolific, our squash selection includes a wide diversity of bush and vining forms. Whether you grow at a commercial scale or are selecting squash seeds for planting in a home garden, we have a variety of options to meet your needs, including varieties with superior adaptation and disease resistance; heirloom varieties, certified-organic seeds, treated and untreated seed; and a range of fruit size, shape, and color — all with superb flavor.
