Cucurbita moschata 'Tromboncino'

squash 'Tromboncino'

A cultivar of butternut squash, mostly used as a summer squash like courgettes, by harvesting the fruits when young, pale green and around 30cm (1ft) long. These have a sweeter flavour and are less watery than courgettes. They are produced on trailing vines, but will also climb if a trellis is provided. Left to fully develop, the fruit become a stretched, narrowly cylindrical, sometimes twisting shape, around 1m (39in) in length, with a bulbous end furthest from the stalk. The hard skin is smooth and pale orange. Ripe fruits can be stored and used in the same way as other winter squash
