In front of my house facing south, I have a flower bed the size. I covert the flowerbed with about 10 dahlia, It make something nice to see and with much trouble.
Among my plant there is 3 that don’t grow any flower, lots of green and very small button, but no flower.
I cannot explain why, since they grow at the same place, same earth, and same care as the other on who are in full bloom.
I think I should get rid these plants.
They are from last year, and I remember they had no flower on them last year.
Any logical explanation?

Thanks all.
