Last fall when I divided scores of my daylilies I also divided some of my older perennials including several Siberian irises.
‘Little White’ had only been sending up a smattering of blooms in the last couple of years, so it was time to give my iris some new life. I divided it into 2 clumps and now they are both blooming happily:
‘Little White’ grows 15 inches tall in full sun to partial-shade and prefers ample moisture.
The pretty, pure-white flowers appear in May and June.
