Peacock Maiden bloomed in late May, it re bloomed for me and provided blooms as late as the middle of September. I made no written notes except for the fact that the plant was sitting very low in my bog garden and I raised it up in October. Even though the crown was very low and it was sitting in a very wet spot, the plant performed very well and I remember thinking how well it had performed under such conditions. It multiplied quite well and showed decent rust resistance.
For some reason I had the hardest time recalling the name of 'Peacock Maiden', I would see it and think how well it was performing but always have to go look at the label for the name.
