near Seattle, very late to bloom, but late August to frost smothered with pale yellowish flowers the bees love. Utterly carefree for me on east facing slope. No pests, no staking, no deadheading, and is drought tolerant. Bigger than label says, when flowering is 2 1/2 feet tall and wide. flowers kinda dull, but still worth it.

This is great to grow with grasses ..it looks good in a more natural or cottage garden..It grows rather untidy.. Flowers appear whole summer and do very well in a vase. The spent flowers can also be used in dried arrangements.
