Seeds & Plants - History Blooms at Monticello - Upper Ground Sweet Potato Squash

Upper Ground Sweet Potato Squash (Cucurbita moschata cv.)

This rare heirloom is a rugged variety that is tolerant of hot, dry weather, rendering it especially well-suited to the South. The vines are vigorous, with large, dark, metallic green-striped leaves, and it produces an abundance of medium-large, round-to-bell-shaped, tan-skinned fruit and moist orange flesh that resembles that of the sweet potato, hence the name. 

In 1790, Jefferson sent to Samuel Vaughan Jr. seed of a melon species resembling a pumpkin and tasting like the sweet potato, calling it “potateo-pumpkin.” The Upper Ground Sweet Potato Winter Squash can weigh up to 20 pounds when ripe.
