Highlights
The heavily striped, light green-grey skin catches the eye before you taste it, but the real revelation is the creamy, sweet flesh inside. Fruits mature in a swift 50 days, and the open-spaced plant structure makes harvesting effortless even when the vines are laden with zucchini. High yields over a long season mean you'll have plenty to harvest at that perfect 5 to 6 inch size, whether you're planning savory gratin or unexpected sweet applications.
Common Uses
Greyzinni zucchini works beautifully in both savory and sweet applications. The fine eating quality and creamy texture make it excellent for grilling, roasting, and sautéing, while the sweet flavor profile opens unexpected possibilities for breads, cakes, and other desserts. The compact 5 to 6 inch size is ideal for the table whole or halved, and the firm flesh holds up well to any cooking method you choose.

Care Instructions
Start Indoors
Start seeds indoors in very large pots 3 to 4 weeks before your final spring frost date. Keep soil warm and consistently moist until germination occurs.
Transplant Outdoors
Transplant hardened-off seedlings outdoors after the last frost danger has passed and soil has warmed to at least 70°F. Space plants 36 inches apart in all directions to allow for the open-spaced growth habit.
Harvesting
Pick fruits when they reach 5 to 6 inches long for optimal flavor and texture. The striped skin and blocky shape make it easy to see when fruits are ready; smaller fruits will be more tender and have fewer developed seeds. Harvest regularly to encourage continued production throughout the season, using a sharp knife or pruner to cut fruits cleanly from the vine. The open plant structure means you can easily spot developing zucchini without searching through dense foliage.
