I am doing some landscaping near the house. I got these landscape timbers so as to keep the lawn out of the area near the house; grass does not grow well in the other area.I am putting in boxwood near the deck to hide the underside, on the other side of the house we will put in rhubarb. I am thinking of what kind of low plant to put in the area away from the house. Maybe heather, my wife thinks even ferns of which we have in abundance for free may be too high; she likes the view. What low plants that get maybe 50% sun or less do you think would work there? They have to be deer resistant.
