Big white plates of flowers to 8", branching stems often tinted red, and lacy foliage, elegantly tiered. Flowers are said to attract a variety of pollinators. Blooms July-September.
Late to emerge from dormancy in spring. Its height can reach 5'.
Best in moderately fertile, moist well-drained soils. Needs consistent moisture. Said to be adaptable as to soil type or pH. Self-sows unless deadheaded.
The American Horticultural Society Encyclopedia of Perennials (ed. Graham Rice) give its hardiness range as Z4-7. As with most plants native to the Himalayas, it's said to hate hot summers, so it may perform best in the Pacific northwest, or in the UK. In eastern North America, I suspect it may be worth trying in Z6. I've read that it can be a miffy plant, but Oudolf and Kingsbury consider it reliable and long-lived.
Another very similar-looking plant that may be more widely adaptable and reliable (and hardier) is Baltic Parsley, Cenolophium denudatum.
With regular water in 9b, this plant takes its time to grow and bloom, a bit over a year for me, but it grows taller than me!

It blooms for 3 months straight, the flowers are self cleaning and the foliage is so finely cut. This plants never looks messy or bedraggeld and takes no care at all besides watering.
It is evergreen where I live.
The flowers do not smell and I never see a bee on it, but they sure please me!
Mine is planted next to my fig, for a bold contrast in leaf.
