So how efficient was hand pollinating the flowers? To the left are the blossoms and to the right are the later seed pods. The blue arrow points out the small seed pods that did not get fertilized. The green arrow points to a fertilized pod. It appears that efficiency could be improved if the pollination process started sooner, when the first blossoms appear. If yellow pollen can be collected, then the flowers can be pollinated. About half of the flowers got pollinated in this experiment.
