Zappallo de Tronco Squash -The Avocado Squash

Zappallo grows upright on the stalk, staying off of the ground and avoiding most squash bug infestations and ground-rot problems. We’ve noticed that once a leaf or fruit of a squash touches the ground, squash bugs seem to appear with a couple of days.

This semi-bush variety is a wonderful cross between a summer and winter squash when young and small with an edible rind and a winter squash once it matures and the rind hardens. The flavor is much better than the standard summer zucchini.

Can be eaten whole when small (2½-4 inches) as a summer squash or left to mature to the fully ribbed state and used as a winter squash. A bushy upright plant with 3-4" acorn type squash with great texture and flavor. Drought-tolerant and quick maturing.

In the summer the squash has a dark green exterior and a light green flesh-similar to a hass avocado. The flesh is very smooth and dry. As a summer squash it does not give off a lot of excess water like a zucchini does.

As a winter squash it is dry, semi-sweet and a relatively short keeper. 

Originally from Argentina where it is loved and found at markets, this variety does well in American gardens where almost all other squash fail. This would be an excellent squash to have in major circulation. It is also called Avocado Squash or Zapallito de Tronco Squash.


Summer Squash is one of the oldest known crops—it was found in 10,000 year old archaeological sites in Mexico. Its cultivation in the southern and eastern U.S. and some highlands of Central America dates back to at least 2700 BC. The remarkable diversity was already present in pre-Columbian times. 


It is used fresh, grilled, cooked in soups or even used in pies.

Growing Tip

Sow 5 seeds per hill, 4' apart. Thin to the best 2-3 plants. Squash seeds dislike cold soil. It's better to wait until the soil is warm to plant the seeds.

    Grew one plant in small garden in north Willamette Valley, Oregon. It sprawled in a lively and lovely fashion and produced absolutely delicious summer squash. My new fave! It’s a must-plant, along with heirloom crookneck squash.

    Every friend i've shared this squash with over a number of years has loved it. I've found squash bugs are not quickly killing it, and although it produces well, it's not overwhelming like zucchini. One friend who tasted it (lightly sauteed) who claimed to be a connoisseur of summer squash, said his "tongue had an orgasm" when he tasted it.
