Only been in my garden since spring 2017. Started with healthy, 2 fan plant from O'Bannon Springs. Only got two blooms last year, scapes about 2 ft tall, but first year divisions are nearly always shorter here. It just seemed to sit there last summer, no signs of increase. Came up with 5 fans this spring and I expect much better out of it this year. Will add more later once I see how it goes.
One of last years blooms.
Lotsa weather fluctuations and a frost this morning, so foliage not perfect. But it's still here and increased to 5 fans. So I'm happy.
