Pumpkins are actually a type of squash which are from the cucurbita genus (family). There are many species of this family, but there are only 4 offered here. (cucurbita - maxima, mixta, moshata, and pepo). There is no need for concern with keeping them isolated from each other, unless you are collecting seeds. If saving seeds, all varieties within a species will cross with each other, but will not cross species.
Bees are essential for pollination, but it can be done manually if problems are experienced.
Note: A lot of squashes which also look like pumpkins, with a squash taste - are listed under squash.
Usually, the larger the pumpkin - the earlier the start date and more space is needed between plants.
Planting Pumpkins and Squash with your Corn will "help" with coon, skunk, and porcupine control.
Because of the large variety of pumpkin characteristics, none are highlighted.

Toad Mini Warty Pumpkin
Warty pumpkins are the current rage. They are so popular that one company tried to get a patent on all warty pumpkins and is even threatening lawsuits against anyone developing more varieties. After trialing all varieties - I found essentially all orange warted pumpkins - no matter what variety name they are given - are very similar. They all generally have green warts which turn orange, as they ripen. Where they do differ however, is in size and shape and quantity of warts.
