"100% pure pumpkin" crows the Libby web site. They announce that they only use "a special variety of pumpkin called the Dickinson." But is that really pumpkin? Experts disagree. For one, it's not orange. The Dickinson Field squash belongs to a species known as Cucurbita moschata, sharing a genus (Cucurbita) with the Jack-O-Lantern pumpkins, but betraying its Halloween-y origins with a decidedly tan skin. A little like the butternut squash - and, in fact, the Dickinson cross-polinates with the butternut.
Despite its tan skin, the Dickinson has that lovely orange flesh you expect from your pumpkin (no artificial coloring necessary). It has all the vitamins and minerals you know and love. It tastes great (and - if you really want to know - those pretty orange-skinned pumpkins? they don't taste so good). It's just that the pumpkin on the label, the one with the bright orange skin, is a bit of a white lie.
