Question

What are the arms for on pumpkin plant?

Answer 1

Maybe you are asking about the "tendrils".   Sometimes attached to the stem are thin, hairlike "tendrils".  During the growing season, tendrils on the vine are green. They twist around objects on the ground to help anchor the vine and protect it from the wind. After harvesting, there are sometimes dried, brown tendrils still on the stem. This gives the pumpkin character, and is viewed as artistic in pictures and drawings, especially a comic drawing like Lord Pumpkin. http://en.wikipedia.org/wiki/Lord_Pumpki...

Answer 2
