I am looking for a good strong ornamental grass. It is to be put in a container to go on the patio next to the pool. It is a very hot sunny spot, sun on it most of the day. Conifers and other hedging means it's a sheltered spot. (in France, so 30 degrees is normal).
It needs to be OK with getting splashed with pool water and I really don't want bits dropping off everyday and ending up in the pool. Also, don't want it growing too fast and outgrowing the container.
I have seen some at a local lake, they have used it to create a walk through down to the beach area, it is a lovely bright green and nice and sturdy. However, I have no idea what it is called.
Would be very grateful for any advice on what to look for and if possible where to get it from. Am happy to grow from seed if necessary, not looking for an instant fix.
