Tromboncino

Tromboncino is a unique Italian summer squash known for its rambling vines and exceptionally long, pale green fruits. Fruits can grow impressively long, with a tiny seed cavity confined to the blossom end, leaving most of the flesh firm, mild, and nearly seedless.

This variety offers excellent flavour and texture in the kitchen and is especially versatile when harvested young. Tromboncino can be steamed, stir-fried, grilled, or even pickled. When trellised, fruits grow long and straight; when grown on the ground, they develop fun, curved shapes.

Fruit and Harvest

Tromboncino fruits are best harvested young and tender at 20-45 cm (8-18") long for use as a summer squash. At this stage, the flesh is firm, mild, and nearly seedless.

If allowed to mature fully, fruits develop thicker skin and can store well into winter, making this a versatile squash that bridges summer and storage use.

Excellent for:

Stir-frying and saut'ing

Steaming and grilling

Pickling

Extended storage when fully mature
