Experts and BHG readers answer.
I have a purple fountaingrass, will it come back, if so, how do I know if it's a prenial or annual? Currently it's in a container-from last year. Need help!!! Thanks you for your help! Mary
Thanks for writing. Purple fountaingrass (Pennisetum setaceum 'Rubrum') is hardy only in Zones 9-10, so in most areas, it's necessary to treat it as an annual.
