Q.Purple fountain grass

Anonymous added on October 19, 2014 | Answered

I bought a purple fountain grass and I don’t know whether it is a perennial or an annual. I really don’t want to bring it into the house, unless I have to. Can you help?

In Zones 5-9, fountain grass is considered perennial. However, they seem to respond better in the warmest areas of Zone 5. They can survive in the ground and come back as long as it does not get colder than 20 F. If it gets colder than that where you are, then this article may help: https://www.gardeningknowhow.com/ornamental/foliage/purple-fountain-grass/over-wintering-fountain-grass.htm
