What is the difference between:

Family:

and:

Scientific Name:
Miscanthus sinensis 'Variegatus'

Plant Common Name:
Variegated Maiden Grass

Family:

Also which is less invasive?

Dear tamlamb - donax is very very tall - have seen it at 15 feet and really not too pretty. The miscanthus is a clumpy, fountain shapped plant. In my experience neither has been very invasive. Hope that helps!

Thanks Plantman I apppreciate you taking the time to answer my post.

Tamlamb, I also want to add that Arundo is not hardy, cooler than zone 7. I know it can make it through in six with mulch. On a personal note, I fell in love with a clump of the Arundo, by a pond at a retail center, until I noticed in it's present location, it comes up variegated and really stunning, but then turns completely green and looks somewhat like corn.
