Pampas Grass

Question

How salt tolerant is Pampas Grass? We want to plant it along a sea wall which is subject to salt water flooding.

Answer 1

Yes it is relatively tolerant of ocean side salt spray conditions. Where I come from on the California central coast it grows right up to the waters edge in some locations.
But be sure you know what you are getting into, it can become quite invasive.

Quote from the following article: "Another plus side to growing pampas grass is its tolerance of drought, wind, and salt sprays—which is why you commonly see the plant along coastal regions."
