I bought this daylily years ago for my mom and divided one clump for her this summer this summer. Truthfully, I took a huge shovelful of clump, brought it home and took it apart. After 4 years in the ground, the half-clump I took yielded about 20 fans. I planted double fans and most of them have fanned out already. I transplanted these babies in early August and they settled in and took off! I had enough left over to give my daughter a potful of Addie Branch Smith too... (infecting yet another victim, er, I mean daylily-lover)
This photo is from the clump prior to division... It's a bit down in the foliage- we'll see how it does here.
