I have P. incarnata growing wild over about 3 acres of pasture, with dozens if not hundreds of individual vines. There is a remarkable degree of variation in the flowers and fruit. I have a composite photo of flowers showing the degree of variation. I can try to post it this evening.

This image shows some of the variation in flowers from a single population. Considering how widespread incarnata is, the variability out there must be huge.

I feel better. mine are all similar to ones you've posted.

As we are in similar zones I should see mine return year after year as yours have, I hope.

I notice that the pistil's on many of the flowers are variable. some have larger pistils and some have very small ones. I have had no luck getting any pollenated by using Incense and Vitifolia pollen, the different Incarnata's I have don't seem to bloom on the same days, so I have not cross pollenated them.

I do have a fruit on Incense pollenated by incarnata, but the squirrels have already gotten 4 I had forming this way, so I am not very optimistic I will get seeds easily.

Chills,

The pistils mainly tend to vary in their position, upright or curved downward. The upright pistils usually indicate a male-only flower, or a female that has not yet become receptive or is well past the receptive phase. Some of the flowers have very tiny, partially formed pistils with reduced ovaries, and are definitely male-only.

I understand that 'Incense' is pollen sterile, but you never know for sure. I have tried pollinating my 'Incense' with at least a dozen incarnatas, perhaps 50 times so far, including bud pollination, without any success. You are at least getting fruit set. You may want to put a sock or stocking over the fruit and tie it to the vine or support with some string.

I'll let you know if the fruit is hollow or good inside (I'm going to tie a stocking over it right now..

Thanks..
