David, the white flowers have the same pistil but it's not as easy to see due to the lack of contrast between the petal color and the pistil color.
See pistil in the red box:
The other sexual structures you see are the stamens (with the purplish anthers on top.)
Many types of flowers will exert their male and female parts at different points of flower maturity in order to decrease the chance of self-pollination and increase the chance of the preferable cross-pollination.
Zuzu, I wondered about the lack of serration at first too, but when I looked closer I saw it. Here are a couple of examples:
I was thinking...some florist carnations often have smoother edges, lightly waved rather than deeply serrated. I wonder if it's just a mutation that can happen when Dianthus are bred.
Although it is pretty enough to be a work of art, it looks completely real to me. The flowers are far too detailed and showing different stages of maturity. (but that's a funny thought about it still being there, Lori.
)
Greene, I saw those too!
I think they are there to get a snack!
I don't know about the rest of you but the more that I look at this flower, the more that I want to grow one just like it!
Jmorth, was the photo taken in a botanical garden or just in someone's yard? Did you take any other photos in the same area where this plant might show up in the background?
