Re: Pennisetum orientale
Janet-
I have about a dozen P. orientale in an exposed area that were planted last
fall. Went shopping last week locally to get more and just found out that
they aren't as hardy as I thought either! We too had a mild winter last
year. Our landscape plans call for about 10 more plants... before I invest
in them, does anyone in my area have experience with these and how hardy are
they?
