novembergrl congratulations on your seed pod! :O) You are correct.. I did a little research and have attached the link for you.

Here is a link that might be useful: info on pollination of plumeria

I have to add that the Monarch butterfly is also a pollinator, at least in OUR yard. My husband has had MULTITUDES (currently, nineteen, with approximately 50 seedlings that he started the other day which all germinated) of what you are calling 'double' pods ever since I started raising butterfliesÂ

The article above mentions Thrips, which we have very few of, however Monarchs we have PLENTY of and they seem to really like the whites and the pinks~{{gwi:1228132}}

Hubby had 19 seed pods last year and has had 19 seed pods this year. HmmmÂmust be those darn butterflies! hehehe

Oh, and here is one of the results of the cross-pollinated flowers, thanks to the MonarchsÂ(from a Cindy Moragne -seed pod- note the shape is of the J.L. Pink Pansy that was sitting RIGHT NEXT to itÂhmm, and 'no cross pollinating' occurs? I don't think so!)

FYI: There are Plumeria that produce more than 60 blossoms per plant (i.e., Guillot's Sunset, Samoan Fluff). :)

As far as ripening? Six to nine monthsÂkeep an eye on it and put a pantyhose on it when you see it get plump and brown and starts to crack so the seeds can fall into the pantyhose. IF the pod is really large (I couldn't see your picture) you may need to reinforce the stem of the pod so it doesn't crack off by using a popsicle sticks like a splint.
