Exceedingly long vines produce fruits that start out green and mature into beige-colored fruits with thick, hard rinds. The soft, orange flesh has a nutty flavor reminiscent of pumpkin. Butternut squash has an oblong, hour-glass shape.
 
Vines are prolific and will produce fruits in a wide range of sizes which happens due to environmental circumstances at the time the flower is pollinated. If you have the room, or the ability to grow vines up a structure, this variety will produce the most bang for your buck. (If you have space confinements, I suggest you grow the Honeynut variety, instead.)
 
Butternut is a winter squash and will keep for months, stored properly.

Sold in 4" pot containing at least 3 vines.
