Does anyone know for sure what the ploidy of "Big Smile" is? I've had this daylily for 3 years now. I want to use it for breeding this year and would love to know. I've searched and Dave's Garden says Tet along with 2 others I checked. I also found 3 places that said dip. My plant looks just like the ones pictured at Dave's garden. All help greatly appreciated, Mona
