John sorry if you were hoping for a sensible reply to your question. Truth is I don't know the answer, but I've got the same problem. I've got some growing in a large container - they're the one's that have gone short, and some against a fence which have stalks a foot long with plenty of flowers up the stalk. I know I had a couple of different varieties, but don't know which were which :-[ Hope a swwet pea grower stumbles by with an answer :)
