Planting perennial flowers in your landscaping is the easiest way to add a pop of color. Jeff Blunkosky, owner of Pittsburgh Stone & Waterscapes, recommends the following perennials:
Black-eyed Susan adds the perfect pop of sunny yellow in this garden.
The Astilbe featured in this garden offers a soft punch of purple to the mostly green surroundings.
Lilies come in a variety of colors. These lilies offer a brilliant splash of orange.
Billowing Aromatic Lavender line the stone stairs leading down to a private patio.
Coneflower sports a daisy-like flower with a raised center.
