Kwanso may have a stunning flower (and that it is) but you do not want to plant Kwanso in your daylily beds or anywhere near them as it will take over everything. When trying to dig out Kwanso even the smallest bit of root left means it will return again.

I had one pop up on one of my late bloomer beds. I very carefully dug up the fans and all the roots. Two years later, here it is blooming again. The plant had regrown from whatever small piece I missed. Again I dug it out. Hope I got it all this time.
