Zucchetta Tromboncino Summer Squash (Heirloom, 60 Days)

The Zucchetta Tromboncino Summer Squash is an 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 as winter squash. A firmer zucchini than we’re used to; the flavor is mild and delicious. Can be grown up a very strong trellis. Tolerates squash vine borer.
