I have a sweetpea outside that seems to be setting 'pods'
I was hoping to gather any seeds and pass them to people as the smell from
these is WONDERFUL....The flower isn't that great.....But its a nice shade
of deep purple....

My mum and a couple of other people have already said that they would like
seeds if I can get them...

So....How should I do it?

Should I gather the pods when they fall off and pass these out?
Or do I need to 'pick' them?
If I need to pick them when should I do it?
