We purchased purple fountain grass last year. Beautiful! Cut down in winter like instructed. So far, it has not come up this year. Nothing! Is purple fountain grass not perennial, but annual? We thought it was perennial.
Is Purple Fountain Grass Perennial

Yes, this plant is a perennial, if you live in a zone where it is hardy. They can survive in the ground and come back as long as it does not get colder than 20 degrees F. However, it sometimes takes a while before it comes out of dormancy, which should happen sometime in late spring to early summer.
