A 1 foot perennial native to the redwood belt east to Montana and north to Alaska. Always in the north slope understory-type situation. Use as a small scale groundcover in a shady moist spot. After they are established they have some drought tolerance, especially in the redwood belt. It is marginally hardy here in containers. It doesn\'t seem to be able to handle winter sun at all. We\'ve made it stable here by planting it where it is protected in the winter by shade. Its cold tolerance is about 15 deg. F., if given overhead protection, maybe 10 F. It is not very drought tolerant. Great near a shady lawn.
