Most use a chemical which is applied to the crown of the plant. It doubles the chromosomes from 22 too 44 to make it a tet. There are a lot of daylilies killed in this process so I let someone who has done it for a while do mine for a better chance of survival. If the plant lives it still may not be a Tet, and may not bloom until the following year. I have waited as long as four years to get one that is Tet. I will pick up one from Florida in March I have waited on for three years. Its a slow process most of the time, this is why some of the conversions sell for $500.
As far as tootie patterns I would think Jamie Gossard already has them. He has done a lot of work with both so I'm sure he is crossing the two.
