Zucchini Costata Romanesco is a traditional Italian heirloom with great flavor. This distinctive zucchini is medium gray-green, with pale green flecks and prominent ribs. Big, large-leafed, semi-vining plants with only about half the yield of hybrids, but much better flavor; clearly better textured, nutty, and delicious, raw or cooked. Also a good producer of heavy male blossoms for cooking. Harvest in 60 days. Germination rate is 80%.

This is an heirloom seed, meaning it has been passed down from generation to generation for at least 75 years. As a rule, heirloom seeds taste better and will grow the same year after year.

These are also open pollinated meaning they will reproduce themselves. While all heirlooms are open pollinated not all open pollinated seeds are heirlooms.

Companion planting is planting seed varieties near each other to benefit one or more of the plants.  Some plants benefit each other by attracting beneficial insects, keeping away unwanted bugs. Others aid in pollination. Some plants have working relationships with each other and others have antagonistic (hostile) relationships.
