While Anemanthele lessoniana is touted for its wind tolerance, it has been more difficult to find information regarding its tolerance of coastal conditions. I have read reviews from gardeners, designers, and homeowners who have had great success planting this grass in their coastal gardens. But just to be safe, I may check with a local nursery or designer who may be more familiar with the specific conditions of your area. These aren't ridiculously expensive plants so if you feel like taking a chance and seeing what happens, you can always try that too.
