I happened to be researching Frankly Scarlet, which is registered as a tetraploid. There is one child plant, Molten Morning. Molten Morning is registered as a diploid. The cross was Frankly Scarlet X H. fluva "Kwanso". " H. fluva "Kwanso" is a triploid. Can someone explain to me how this happens--obviously, I know nothing, but would like to know. I thought triploids were sterile.
