Oh Terry, I so envy you! It would be very nice indeed to have a budding buddy hybridizer doing it with you! Even better if it is one of your children. You are truly blessed. I don't think I am going to have that family support from mine. Neither DH nor DS has any interest in gardening.
I think Ashton is going to make a name for himself someday! He sounds like a child prodigy in daylilies hybridizing. By working with and being around daylilies all his life, I think he will develop some sort of a 6th sense or advanced understanding of the nature and behavior of the plants.
