Winter Squash - Black Sweet Potato


Cucurbita argyrosperma

HEIRLOOM. Cushaw type. Has a sweet buttery taste comparable to a butternut. We made a few savory pies out of it and it was super tasty. Has a thin wall of pale orange flesh, about 1" making it a nice, speedy roaster. Large pear shaped fruit with smooth skin that is dark green with orange-ish yellow markings. Fruits measure 12-16.5" long, 8.5-12.5" in diameter at the widest part, and weigh up to 20 lbs.
