There are two types of Squash - Winter and Summer. One of the major differences between the two, is that Summer Squash is usually picked when immature (less than 50 days from planting), where as Winter Squash is picked when its completely mature (100 days or more after planting). Summer Squash has thin rinds that are edible, and does not store for long periods of time. On the other hand, while Winter Squash has thicker rinds, it can keep for up to several months.
The long shelf life of Winter Squash is one of the reasons why it got its name. Winter Squash can be stored for weeks, even months - like a long, cold winter - in a cool, dry place.
Butternut Squash is one of the most popular varieties of Winter Squash. It is a great source of fiber and potassium. A cup of Butternut Squash (cubed) provides more potassium than the amount typically found within a medium-sized banana.
Butternut Squash improves digestion and immune systems, lowers blood pressure, and makes for healthier skin and hair.
In addition to food, many Squash were grown to be dried - and used as functional items. In their early days, Squash made for great containers. Sioux Native Americans would cut Squash into strips, dry them, and weave them into mats.
