Salvia argentea - Silver Sage

Salvia argentea has wooly leaves that look like they belong on another planet, or at least pulled from the set of Arachnophobia. The flowers are white and fairly nondescript. Salvia argentea plants are biennials, flowering in their second season. They require decent drainage and are often rotted by overhead irrigation. New plants will occasionally come up from seed and I sometimes get a plant to come back from the roots by cutting off the flower stalk before it sets seed. Silver Sage has been hardy into the teens here. Salvia argentea is native to southern Europe.
