I also posted this in the Ornamental Grasses forum:

Hello, I am trying to find out if Miscanthus sinensis 'Gracillimus' will live in Mobile Alabama. We have a project down there and right now they have Panicum virgatum 'Switchgrass' specified. I have absolutely no experience with Switchgrass and the only pics I can find of it make me think it looks weedy...apologies to those who may love this grass. Anyway, I have tried to replace the switchgrass with Miscanthus but the LA in charge is saying it will not live in Mobile. Everything I can find on the miscanthus says it is hardy to zone 9. Does anyone have any experience with this particular Miscanthus in lower alabama or the gulf coast? Or any other information on the Switchgrass will be appreciated also.
