Naming

Agrostis perennans was already described and the name validly published by Thomas Walter. It was Edward Tuckerman, however, who reclassified it into todays valid botanical systematics in 1843.

Distribution

They tolerate temperatures down to -35°C (USDA zone 4) and need a frost-free period of at least 17 weeks.
