How to overcome plant sterility
Here recently I have grown a number of hybrid petunias as well as calibrachoas and wish to get seeds from them. I realize that many of these, the calibrachoa especially, do not make seed and if they do then they are not true to the parent plant.
Despite this I still want their seed because I would just like to see some of the traits the seedlings possess. The problem is, I have not been able to get a single seed pod from any of these plants! I understand that most of these are propagated vegetatively but there has to be a way for them to make seeds otherwise there would be no way to get these unique characteristics in the first place.
So I guess my question boils down to how in the world do I get these guys to give me some seeds????!!
