Obsession: Fall’s Golden Grasses

Not only is their coloring valuable at this late season, but the slender foliage and flowery plumes of ornamental grasses adds distinctive form to the garden’s autumn palette. They may begin the season in shades of green, but each of these turn a warm, golden hue in fall. Tough, unfussy, waterwise once established, they’re picture perfect in beds, borders, on slopes, and, with the taller varieties, as soft hedges.

Here are ten of our favorites; plant them now for a show that starts early next summer and, for many, runs right through winter.
