Richard has registered a couple of polymerous daylilies. (Sadly, he is not into hybridizing for that trait, so I doubt that we will see any more polys from him.)
Hip to Be Square
(This one sometimes swiftly reblooms here, but it is not a consistent trait. My overgrown clump starts flowering late May as a rule; it is currently still going on the rebloom scapes. This cultivar is both pod and pollen fertile.)
Polly Wolly Doodle
(This one starts flowering earlier than 'Hip to Be Square', and has larger flowers. The downside is that the clump also finishes blooming quicker. I would describe the flower as being yellow, rather than gold. Pods can be a bit difficult for the hybridizer to set (the pistil is often blunt or kinked), but the bees seem to manage the feat occasionally. Persistence is called for if you want to use it as a pod parent.)
