55 Golden Zucchini Summer Squash Heirloom Vegetable Seeds

Golden Zucchini Summer Squash non-GMO seeds (Cucurbita pepo), also known as Golden Zucchini or Yellow Zucchini, are a classic warm-season vegetable prized for their vibrant color, fast harvest, and reliable garden performance. This heirloom variety reaches maturity in just 55–65 days, making it an excellent choice for gardeners seeking quick and consistent summer yields. The plants grow in a compact bush habit, making them suitable for smaller garden spaces. Seeds germinate in 4–14 days when soil temperatures reach 60–85°F. They can be directly sown outdoors after the final spring frost or started indoors 3–4 weeks earlier for transplanting. Plant seeds about 1 inch deep in fertile, well-drained soil. Golden zucchini produces continuously until frost when harvested regularly. For best flavor and texture, harvest fruits before they exceed 18–24 inches in length, as overgrown squash can become starchy and less palatable. Frequent harvesting encourages ongoing production throughout the season. This zucchini variety is highly versatile in the kitchen. It can be sautéed, baked, fried, grated into breads, or used in casseroles. The edible squash blossoms are also considered a delicacy. These non-GMO, open-pollinated heirloom seeds are ideal for vegetable gardens and sustainable growing practices.
