Pumpkins?

Could you identify these for me please, they are growing in my son's lawn.

 

Maybe a Sweet Dumpling squash, or a hybrid

 

Thanks @Scrungee, I presume they are edible then?

 

Have had a Google on poisonous squashes but yours don't look like the bad types. But there's only one way to find out.

Invite someone you intensely dislike over for dinner and serve them your 'organic squash' as a starter. If they don't have any severe reactions (or die before the After 8 Mints are served), you might have a delicious delicacy to enjoy later on .

 

There's a problem here @Mowerman. They are growing in my son's garden and he lives in America.

 

Just pass my advice onto him

 

Is the perceived problem being Gourds crossing with Squashes? And the resulting hybrids would be so bitter it should be obvious it's not a good idea to eat them? And if so it would just be tummy aches?

If worried just cook a small piece and check it's just a normal, sweet Squash.
