Landscape designer Stephen Suzman likes the groundcover species Senecio mandraliscae for its fast growth and distinctive chalky-blue fleshy foliage. A native of South Africa, it grows 12 to 18 inches tall with masses of 3- to 4-inch pencillike leaves. greatgardenplants.com
A vibrant groundcover for the shade garden, Lamium maculatum ‘Anne Greenaway’ forms a 6- to 8-inch-tall mass of scallop-edged variegated leaves that glitter with chartreuse, silver and mint green. Clusters of small lilac-mauve flowers add to the display in late spring, but the foliage can last all year in mild-winter regions. Perennial.
Often called pork and beans or jellybean plant, Sedum x rubrotinctum is a 6- to 8-inch low-mounding groundcover with fat little leaves that go from bright green to red. Suzman calls it “very easy and reliable.” The glowing hues of Sedum rupestre ‘Angelina’ have made it a must-have for containers and perennial borders, with needlelike chartreuse to bright-gold leaves usually tipped with orange. greatgardenplants.com
