About

Cucurbita moschata 'Tromboncino' is a type of butternut squash primarily enjoyed as a summer squash. It is best harvested when young, typically pale green, and approximately 30 cm (1 ft) long. These immature fruits offer a sweeter taste and a drier texture compared to courgettes. The plant grows on trailing vines but can be trained to climb a trellis for vertical gardening. When allowed to mature fully, the fruit takes on a long, narrow, and occasionally twisted form, reaching about 1 m (39 in) in length, with a bulbous end opposite the stem. The skin is smooth and pale orange in hue. Once fully ripened, these squashes can be stored similarly to other varieties of winter squash.
