SWEET PEAS & PEAS IN SAME CONTAINER?

Don't see why not, it'll probably encourage the pea flowers to be pollinated as the sweet peas perfume will draw the insects! Just make sure you water it plenty. Sweet peas are also greedy, so lots of feed will be needed.

lovely with the bonus of inticing polinaters great idea! :o)

I grow them with runner beans as they grow to a similar height. Havnt grown peas before this year so i dont know how high they will grow.

Yes that's a good point, they are different heights - edible peas being about thigh high maximum, sweet peas grow over my head (i'm 5'4'')
But I still think it's a good idea. Why not?
Make sure your they both have good support as they grow. Sweet peas grow very tall. Sorry if I'm telling you stuff you knew already.

if in doubt give it a try why not.
