I have only been able to get loefgrenii to fruit with their own pollen and amethystina 'Minas Gerais'. Choconiana, serratifolia, and spruce have not been successful. Numerous crosses from amethystina, Byron Beauty, cincinnata, cyanea, gibertii, violacea, and vitifolia have produced seed. Test germinating currently to see what may be viable. Anyone interested in exchanging please e-mail as the list is too long, and some crosses have very limited quantities.

I believe there are two versions of p.loefgrenii, corupa and iporanga. One is self fertile and thus is not receptive to pollen, the other is not and accepts pollen. I believe it is corupa that is sold by Annie's Annuals and Grassy Knoll that is receptive to pollen, however it is small of the two. Morning Glory don't you have p.'Panda'? Mine is very receptive to pollen. I have fruit on 'Kew Gardens, Panda, Lunametista (another receptive plant), Vitifolia, Lady Margaret (Incarnata works good on this), Anastasia, Purple Tiger, Party Time, Byron Beauty.

PassieFarm if you have p.laurifolia, try it on p.serratifolia. On facebook there is a grower that claims to have successfully used its pollen.

Retired Florida: Thanks for the tip. Cincinnata is the only cross to produce fruit on serratifolia so far, waiting to see if anything germinates. The loefgrenii I have is the species (seed grown), not labeled as 'Corupa' or 'Iporanga', although it could have originated from one of these.
