I can honestly say the 'Fol De Rol' has the most rapid increase of all the daylilies I grow. It's the nearest thing I have to a garden thug. It's a beautiful large bloom but a plant I have not been able to set a pod on, and goodness knows I have tried and tried again. There are 13 children in the AHS database, all with Fol De Rol as the pollen parent, so I am assuming it is pod sterile. It's an easy care plant, can take abuse, and still bloom its heart out.
