Gentle Shepherd is perported to be the purest of the whites; however it is a very week plant. I have had it for seventeen years and it has never done well. I would suspect the site except daylilies growing around it flourish. My Gentle Shepherd sends up two or three spindley scapes each year with low bud count. One year it didn't bloom at all. In my view the blooms are pretty ho hum. I think there are are many better whites to choose from these days.
