Beautiful Lakota Squash!
Here a pair of Lakota squash persist through the summer. These were the only fruit to have actually grown, as all other smaller squash aborted. With the name, Lakota, it's referencing the native Americans who had lived in the area in which the squash was thought to be selected for its traits. Having been around for 100 years this heirloom variety probably prefers slightly cooler temperatures as other growers have also experienced a low yield.
