My father tried to get me some seeds from his Balloon Flower (platycodon
grandiflorum) in July by cutting off the seed pod while it was still green
with the flower wilted, but still attached and not yet dried up.

I don't think there are any seeds in the 'pod' and am thinking he might
have to wait until the pod turns brown and dries while still attached to
the plant.

Am I correct?

Thanks!
