Dark Green Zucchini Organic Squash Seeds. This bushy summer squash will be loaded with 30-75 cm (12-30″) fruits. We suggest picking the fruit when it is small for best flavour and texture. Larger fruit are excellent for making muffins and bread. While this zucchini does not run, it can still take up a decent sized space in the garden of 150 cm square (5′ x 5′).
