The flower below was actually at a stage we call petal fall, the flower has been pollinated (you can tell because the anthers are all brown, indicating that the pollen has been released). It was probably in full bloom a day or so before the picture was taken.
Ouachita, Osage, Navaho are all at the red stage. Von was the only cultivar that still had only green fruit.
In this little trial, we are determining how long it takes a group of five berries to progress from a flower to a ripe fruit. Fruit in the field are at a range of stages. We have been picking Natchez, Osage and Ouachita in our research plots for over a week.
