Cocozelle Zucchini

Cucurbita pepo

Also known as: Cocozelle di Napoli, Cocozella di Napoli, Italian Zucchini


One of the oldest documented zucchini in cultivation — an Italian bush type from the Naples region, carrying long, slender fruit boldly striped in alternating dark and pale green down the length of the skin. Flesh is firm, creamy pale, and nuttier in flavour than a standard bush zucchini, holding its shape well in the pan and grilling beautifully. Best picked young at 15–20cm, though the fruit stays usable to 30cm before turning seedy. A handsome plant, a distinctive fruit, and one of the classic Italian home-garden zucchini. Bush to open bush habit — a little more room than a compact bush zucchini.

Growing notes

A warm, sunny position suits it best. Cocozelle starts producing quickly once the weather warms and rewards regular picking through the season.

Soil preparation: Well-rotted compost and aged manure worked in before sowing. Zucchini are heavy feeders, so build the bed generously.

Sowing method: Sow 2–3 seeds per station 60–90cm apart, either direct into warm soil or into large pots for transplant, then thin to the strongest seedling per station.

Support: None strictly needed, though the slightly open habit can benefit from a low stake if the plant sprawls under a heavy crop.

Containers: Suits a large pot of 40L or more. Keep water and feed consistent, as pots dry out faster than beds and zucchini are thirsty croppers.

Watering & feeding: Deep, consistent watering at the base — like other summer squash, susceptible to mildew, so keep water off the leaves. Side-dress with well-rotted manure or a balanced liquid feed once flowering starts.

Harvest: Pick every two to three days once fruiting begins, cutting fruit at 15–20cm for the tenderest eating. Cocozelle holds its texture longer than a standard bush zucchini, staying usable to 30cm, but pick regularly to keep the plant productive. Fresh use only — this is a summer squash, not a keeper.

Timing: First fruit ready 50–60 days from sowing.

Key features

  • Distinctive dark-and-pale-green striped fruit
  • Firm, nutty flesh — richer flavour than a standard bush zucchini
  • Long usable window before fruit turn seedy
  • Compact-to-open bush habit
  • Well suited to small gardens and large containers
  • One of the oldest documented zucchini varieties

Short season tips


Direct sow into warm ground from mid-spring to early summer once frost risk has passed. In Coonabarabran and similar inland zones, that means mid-November onwards. If time is tight, start seed indoors in large pots 2–3 weeks before transplanting — cucurbits resent root disturbance, so handle carefully and move on with the root ball intact. A staggered sowing three to four weeks after the first extends the picking window into autumn.

Annual

  • Corn, climbing beans, nasturtium, borage, marigold
  • Potatoes, other cucurbits within cross-pollination distance if saving seed


A traditional Neapolitan bush zucchini, documented in the Italian seed trade by the mid-1880s and grown in southern Italian home gardens for generations before that. Its name comes from the Italian cocozella, a regional word for the young summer squash still used in Campanian dialect. Carried outward with Italian migration through the twentieth century, it has become a favourite of heirloom gardeners around the world for its striped fruit, firm flesh, and depth of flavour — a reminder of what a bush zucchini could be before commercial breeding pulled the type toward uniformity.
