Mazus reptans (Scrophulariaceae)
This low groundcover carpets partially shaded areas with a dense, lush 1-2" mat of tiny medium-green leaves. Diminutive soft blue flowers top the foliage in mid-spring and last for 6 weeks or more. Each 3-lobed blossom has a small blotch of yellow in the center. An excellent choice for tying pavers together or tucked beneath shrubs and trees. A mass planting of Blue Mazus forms a soft bed and can be used as a lawn substitute for small areas.
