I have spent several days studying the phlox's anatomy and have finally figured out where the stamens, anthers and stigmas are. So now I'm going to try it, even though all I have are two old varieties and an invasive wild one. This AM I was pulling apart a blossom and realized that the pistil and stigma were left, but the flower was emasculated so I think all I will have to do is dissect a flower from another clump and use the anthers. I can't see how you could mark one flower so maybe use a whole flower head and attempt to pollinate every flower in it. Now all I have to learn is how to harvest, germinate and grow the seed---I may get bored before I get there. I did manage to get seeds from Hemerocallis minor and H flava this month so I can play with them for a time. Too much rain caused deformed seeds though, so we shall see.-------------------------------------------------------Weedy
anyone try crossing phlox??
Just out of curiosity, what species of Phlox are you planning to breed? According to Wikipedia, there are 67 species of Phlox, so there are a lot to pick from, and probably some opportunities to make inter-species crosses.
About 20 years ago I became interested in Phlox drummondii, because the cultivar "Twinkle Star" looked so good in my flower beds.
I purchased several varieties of annual phlox to cross with Twinkle Star, in hopes of getting much larger plants and flowers. One quaint variety was "Phlox of Sheep".
I think it was Thompson & Morgan that I purchased my "Phlox of Sheep" from.
My project to cross Phlox of Sheep with Twinkle Star taught me that I didn't like stooping over to cross-pollinate plants that grew only a few inches tall. I shifted to zinnias because the plants and flowers were much taller and larger, and basically easier to work with. But best wishes to you with your Phlox project. I think there are a lot of opportunities there. I would be delighted to get a zinnia bloom that looked like Twinkle Star.
Ended up with about twenty ripe seeds. I suspect they will have to be stratified or winter sowed and I will have to live until I'm eighty to see them bloom. We shall see!------------------Weedy
