Ambiorix I and I think ALMOST everyone else reading this are very glad that you posted this warning. The pollen on antho varieties can be very fine and powdery and abundant, and I DO NOT want promiscuous pollination of my true growing cultivars. I value being able to grow a seed and get exactly what I was hoping for.
Joseph, I welcome you to plant loads of blue varieties to get your promiscuous pollination, I just know your customers are going to buy lots of those blue tomatoes!
Seriously Ambiorix, thank you for warning us of this danger.
