Location; Whidbey Island in WA State
Whete planting; multiple (7-10?) attractive, low maintenance, beach graph to plant in front of a 28” high deck overlooking the beach. Beach grass would hide mot so attractive space under the deck. Beach grass needs to be about 3 feet high. Could go to 4 feet but no higher😀 any suggestions are greatly appreciated.
