    Hardy in USDA zones 4 to 8. It grows 1-1/2 to 2 feet tall and produces sturdy, rose-lavender flower spikes in midsummer. It has soft foliage, but the color is glossy green instead of silvery white. The flowers are loved by butterflies and hummingbirds, but not by deer.

    The plant grows best in full sun in well-draining soil, and benefits from being divided every three to four years.
