Bluegrass Memories is a real beauty, very hardy in zone 6b and survived below zero temps last winter. I know it is pod fertile as I have many seeds from it to plant this Spring. The color is outstanding in the morning, fades a bit in the afternoon sun. Multiplies slowly but I have divided it once in 3 years. It is unique and always stands out in the garden, I think it looks gorgeous in front of purple coneflowers
