For the last forty years, several Kwanso plants have been peacefully co-existing in the midst of my long and steep roadside bank of H. fulva. They have neither taken over nor diminished in prevalence and have grown without much attention, other than removal of spent flower stalks.
These plants have faithfully prevented erosion of the hillside all these years, and I always love to see them in bloom. Yes, I know they are ditch lilies, but I love them just the same.
