This is another item I picked up from
ebay.
I just put 4 transplants in the ground today and can tell already these are vigorous vines.
According to
Wikipedia one plant can produce 50 fruits!

In reading up on it, it seems to have significant benefits including being arguably the longest storing squash - 2 years with no special treatment. And it gets sweeter with time. According to
this site
"This species is another
cool-climate (but not frost-tolerant) member of the genus Cucurbita and is the only
perennial among commercial cucurbits. It is
pest resistant and short-day flowering. In some places, the rampant, irrepressible vine runs wild, climbing trees and shrouding shrubs with its figlike leaves. Its elongated or globe-shaped
fruits may weigh 11 kg.
Cultivated extensively in the Andean highlands—mostly at 1,000–2,000 m elevation 8 —the
young fruits are used like zucchini. The mature fruits are
prized especially for desserts, usually cooked and served in sweet syrup. They are also fed to domestic animals (horses, cattle, and sheep) during the dry season.
No fruit anywhere keeps as well as these. Mature, they are commonly stored (kept dry, but without any other special care) for
two years, and yet their flesh remains fresh and actually gets sweeter with age. They are eaten boiled or in preserves. Immature ones can pass for zucchini in looks and in recipes. Especially delicious and nutritious is a pudding made by simmering this squash with milk and cinnamon.
The
seeds are baked and eaten like peanuts and are greatly appreciated. They have an
unusually high concentration of oleic acid, the prime ingredient in olive oil. "
Again full disclosure, I've arranged with the ebay guy to get a credit if he gets enough orders. Please send a note to him with "Ref SE" if ordering.
