I had this plant in my last zone 5 garden, and it thrived on neglect in poor, lean, dry, pebble-ridden soil, and very little sun. It required zero effort on my part, and it was gorgeous, although it started rather late in the season. I'd suggest planting it where you can see it from the house, as it may start beyond the usual garden-stroll season. My latest attempt with this plant failed, but I suspect I planted it too late in the season for it to successfully survive the winter. I will try it again, as my previous experience was that it was a delicate looking, no brainer plant.

Lovely, reliable fall bloomer. I look forward to it's cheerful, white blooms in September and October. Great cutting flower.
Not invasive here in Pittsburgh. In fact, it's a little reluctant to get started and divisions are slow to catch on, but patience is rewarded with a beautiful show of white and yellow.

36"-42" Extra large single white. Long blooming.
2" flowers on tall stems are freely and continuously produced. Likes moisture, and needs winter protection in the most northern states. Deer resistant. Good for cut flowers.

Atlanta - can be slowly invasive - sends out undergraound runners and small "plantlets" are easily pulled up. My oldest plant was huge this year - flower spikes 4 - 5' high. Very pretty leaves.
