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.

A vigorous grower that will spread like a ground cover, can be used to fill troubled spots/hard to grow spaces. Can also be used to line driveways, alongside fences, roadsides and in ditches.
Keep away from other clump forming daylilies.

We had a daylily growing thickly in several places in our yard. I believe it is double when it actually flowers, so must be this cultivar, but it doesn't bloom very often. Now most of it is gone, because it doesn't bloom enough and spreads way too much.

I have the 'Kwanso' with variegated foliage I received Sept. 2017 in a daylily trade. It stands out amongst the 20 other varieties growing around it because of the unusual cream and green striped foliage. The flower is the same as my regular 'Kwanso', tall and double. The foliage is evergreen here in zone 9 and the plant blooms in mid season, June/July, like my other 'Kwanso'.
