I tend to go with natural grasses on my floating Island. I take what is in the yard and what is around the area and use them as a starting point. You can add just a touch of Mulch to the top of your shade cloth to start the grass seeds or plants on. To me if you add non native plants on the island it just looks kinda strange. Thats why I went with natural plants.

Here are a few threads that may help.
