Cucurbita Moschata
Butternut squash (cucurbita moschata), sometimes known in Australia and New Zealand as butternut pumpkin or gramma, is a type of winter squash that grows on a vine. It has a sweet, nutty taste similar to that of a pumpkin. It has tan-yellow skin and orange fleshy pulp with a compartment of seeds in the blossom end.
When ripe, it turns increasingly deep orange, and becomes sweeter and richer.
