Getting Pennisetum through the winter?
I’m not a big fan of grasses so I’m afraid I don’t know much about them, but I do like Pennisetum. I’ve had them dying in the ground before, winters can be very cold here, as low as -8c, but not usually wet.

Are they OK without light? Do you just forget about them or do they need some moisture?
Any tips about care in general but especially overwintering would be gratefully received, as I have just bought several large specimens of this one, Pennisetum advena ‘Rubrum’:
