Zucchetta Tromboncino Summer Squash (Heirloom, 60 Days)


Italian Heirloom. This tasty zucchini grows like squash and will need a lot of room for its 15’ runners. Light yellow-green fruit is slender with a bulbous end and should be harvested at about 10”. Leaving it on the vine can produce variously twisted squash specimens 3’ long and 6” wide and can be used like a winter squash. A firmer zucchini than we’re used to; flavor is mild and delicious. Can be grown up a very strong trellis. Tolerates squash vine borer. 

20 seeds


Cucurbita pepo

Germination: 4-10 days

Germination Temperature: Optimum soil temperatures 70-85ºF

Seed Sowing Depth: 1/2-1" deep

Sowing Indoors: 3-4 weeks before last frost. Provide 70-85ºF soil temperature. Sow 2-3 seeds per cell/pot. Sowing into individual biodegradable peat/cow pots reduces root damage when transplanting. Transplant 36-48" apart after last frost. 

Sowing Outdoors: Sow after last frost when soil temperature is over 70ºF. Sow a few seeds every 36-48". 

Harvest: Check and harvest a few times a week. Cut or kindly twist off fruit, starting at a 3-4”.

Tips: Plant in fertile soil, amended with compost or well rotted manure and keep well watered. They benefit from growing on black plastic and by using row covers for weed, insect control, and more rapid growth.

Great Zuccini like squash

Grows fast and produces all season. Its taste is similar to zucchini. I use it to make zucchini cake and bread. They will grow in lengths over 24" if you let it. Pick it when it reaches about 10 to 12 inches for best flavor and tenderness.

Summer “sleeper”

Every year we like to add a different variety of plants to grow along with our standard crops. Although I noticed that this zuccheta was a pretty vigorous grower I ignored it for a long time because it was “weirder“ than my yellow and zucchini squash. It took a couple of attempts cooking it, mixing it in with the other summer squash before I noticed its unique creamy texture. I’m surprised more people are not aware of this awesome tasting squash. I will definitely be growing it again next year.

Our first time to grow Zuchhetta

This has been a fun experiment with a new variety of squash. The biggest appeal is that it is bug resistant. It tastes great and is a conversation item in the garden.

very versitile

Been growing this squash for years. You can use it as summer squash or let them grow huge and use them as fall decoration and winter squash. I also like them because they do not succumb to the insects as easily as other squash plants. You must have a strong fence or trellis and lots of room....
