Lady Margaret will set fruit with caerulea or incarnata pollen, but it's often hollow or with only a handful of seeds. If you're looking for edible fruit, you're out of luck, unfortunately.

thanx jblaschke...u are very helpful...not looking foredible fruit just seeds,now will lady maggie pollenate any passie?i tried to get pollen but got such a small amount very difficult.how about miniata?does that bear seed fruit?

I know for certain margaret & l. lady do, as i've caused it. I think with caerulea pollen, but I don't remember.
Margaret is useless as a pollinator though- At least mine was.

You can check out pictures of my 3-yr old P. miniata plant, flower and fruit(4weeks) on my flickr page, nagwagi2000, victor. Yes it is possible for P. miniata to bear fruit...

Well, just to clarify matters, p. miniata is a full-fledged species formerly known as p. cocinnea. Which served as one of the parent plants (along with p. incarnata) that resulted in the popular Lady Margaret hybrid.

Lady Margaret doesn't produce pollen. It can't pollenate anything. It will bear fruit with occasionally viable seed when pollenated by p. caerulea, p. incarnata and p. vitifolia. Since p. vitifolia and p. miniata (coccinea) aver VERY closely related, and p. miniata is already a parent of Lady Margaret, I'd expect p. miniata pollen to induce fruiting on a Lady Margaret plant. I haven't seen that cross confirmed, but I think the odds would favor it.

Any resulting fruit is likely to be mostly hollow with only a few seeds, however.
