Are certain types of pumpkin poisonous?

However, a few types of pumpkin should be consumed with caution. We are talking about the decorative pumpkins, which delight the eye of the beholder with their decorative to bizarre silhouette. However, they are not suitable for consumption because they contain toxic cucurbitacin.

The focus here is on crown and claw pumpkins with the popular varieties 'Autumn Wings', 'Shenot Crowns' or 'Bicolor Spoon'. With other varieties, such as the well-known 'Bischofsmütze', the pulp may very well be eaten, while the skin is inedible.
