drooping heads

this is the female ovary that is swelling as the plant has been successfully pollinated and the ovules [eggs] have been fertilized. Leave it alone and it will ripen and you will get seed from it.
and welcome to GoY too.

thanks for that seaburngirl....i wondered too what the bulbous things were,,,would the seed be difficult to germinate?

No they are quite easy to do. wait until the pods are ripe and split. collect the seed and then sow in a quality compost.
