Tennessee Sweet Potato Pumpkin
Cucurbita argyrosperma Callicarpa Group

95 days — A very old pumpkin / squash variety. Back when this was a new release, pumpkins were for eating. These do not look like what we would consider a "pumpkin" in this Jack-O-Lantern day and age. The fruit are pear-shaped with creamy, white color skin that is striped in faint green. It is an excellent keeper; if stored properly it can last over six months. The flesh is light colored, fine grained, very dry and resembles sweet potatoes in flavor. Makes an excellent pie. Fruit average ten to twenty pounds in weight.

It is said to have first been listed in 1847 by New York seedsman Grant Thorburn as 'Green Striped Bell' and then, most likely re-named by W. Atlee Burpee in 1883[1] to 'Tennessee Sweet Potato'. Other synonyms used over the years include, 'Genesee Sweet Potato', 'Virginia Sweet Potato', and simply, 'Sweet Potato'.  Whether it was simply renamed or possibly a selection of the original, this is what Burpee had to say in 1883 and it still holds true today:
"Grows to medium size, pear-shaped, a little ribbed, color creamy white, sometimes lightly striped with green, flesh thick, creamy white, remarkably fine grained, dry and brittle, and of most excellent flavor. Hardy, very productive, and keeps perfectly sound until late in the spring, longer than any other pumpkin. It speedily becomes a general favorite wherever it has been introduced. Has no equal for making pies and custards. When cooked it has somewhat the appearance of sweet potatoes, but of more delicious taste. It proves very distinct and fixed, and is a valuable acquisition. This variety we recommend as being superior to any other variety of pumpkin for cooking purposes in cultivation. Its attractive appearance makes it a specially valuable kind for the market gardener. Our stock of this variety is grown with special care, and cannot fail to give satisfaction to our patrons, but the seed being very scarce, we can sell it only in packets. Do not confound the Tennessee Sweet Potato Pumpkin with any other so-called Sweet Potato Pumpkin."[2]
Our original seed sample was sent to us by David Pendergrass in Middle Tennessee, whose seed originated from USDA accession number NSL 5197. Rare and in limited supply. Each packet contains two grams, which is approximately 10 to 15 seeds.


Although the name or description of this variety refers to a modern company's name, the seed we are offering is in no way sourced from, "owned by" or connected with that company. The name is simply the historically accurate, common name for the variety giving credit to the seedsmen that originally released it.
Planting Instructions: After all danger of frost is passed and the weather has warmed, plant four to five seeds, 1 inch deep, in hills spaced 6 feet apart. When seedlings are 2 inches tall, thin to 2 plants per hill. Winter squash prefer rich soil. Feed at planting time and again at the 4 to 5 leaf development stage.

Keep watered during the dry weather and cultivate or mulch to reduce weeds.

★★★★☆ Extremely vigorous, mild taste
By Shelah (Weld, Maine) on November 17, 2022

We've had drought the past four springs, which means our short season (zone 4b) loses about a month. Our summers are cool. I planted three winter squashes (butternut, buttercup and red kuri) and the Tennessee Sweet Potato pumpkin this year and only the pumpkin did well; the others yielded about the size of a baseball or less. We planted the pumpkin against the chain link deer fence and it loved the trellis; this vigorous vine had several big pumpkins hanging in mid-air. As to the taste and texture, it is nothing like a sweet potato; it's closer to a yellow summer squash. The skin is hard and it remains hard after steaming, but the flesh scoops out easily. The flavor is delicate and mildly sweet, not bitter at all (as opposed to the luck of some other reviewers), but nothing you'd consider to cook like a pie pumpkin, or really any pumpkin or squash recipe I can think of. After puzzling what to do with it (because it grew well and I have a lot!), I found that if you mix it with potatoes, butter and cream, it makes a terrific version of the Irish dish Colcannon.

★☆☆☆☆ Awful bitter
By Mike (Wi) on October 2, 2022

Was excited to try these. Cooked one up to make a pie. Tasted fit as the fruit was lighter than a “squash”…… BITTER!!! Very disappointed. Absolutely not even close to sweet potato

★★★★★ WOW! Just... WOW!
By Ms Pony (Zone 6) on August 24, 2022

First time we've grown these pumpkins, and we are mightily impressed. The vines are sturdy, and looooong! The deer and insects did not bother them at all.

Don't know how well they will store, because this is our first year growing this, but I am fairly confident that they will do well.

Neighbors are already asking for seed. :)

★★★★★ Nice pumpin
By Anne Holzinger on September 10, 2019

Grew these for first time this year. This was easy to grow, handled weed pressure well and produced very large fruit. I will definitely grow this again.
