Great ground covers look pleasing from season to season. ‘Eco-Lacquered Spider’ boasts shiny green-and-gold foliage that is purplish in winter and accented by tiny yellow flowers in spring.

Some creepers love the sun

Golden creeping thyme (Thymus X citriodorus “Aureus’) looks dainty, but it’s a tough and fast-growing ground cover. I use it to rapidly fill in gaps between stepping stones or rocks. It grows to only 2 or 3 inches high with tiny leaves about 14 inch wide and long. In early summer it bears small, delicate, whitish flowers. Mostly evergreen, the foliage starts with  strong golden overtones and turns greener in autumn. In winter the stems take on reddish tinges. Like other thymes, golden creeping thyme is aromatic, releasing a slight lemony scent when touched, and can be used in cooking.

Another robust creeper, golden oregano (Origanum vulgare ‘Aureum‘) holds its golden hue best in colder weather. A useful culinary herb, golden oregano has tiny, rounded leaves 1/2 to 1 inch wide. Its small, lavender to purple flowers stand out above the foliage in early to late summer. Combine it with other oreganos, or plant it under lavenders (Lavendula spp.), rosemary (Rosemarinus officinalis), or Japanese bloodgrass (Imperata cylindrica ‘Red Baron’) to provide a contrasting carpet of gold.

Use golden creeping thyme to spread quickly around stepping stones. Its leaves release a lemony scent when brushed.

These spreaders are at home in either sun or shade

Ground-hugging Mazus reptans fills in neatly around rocks. Its tiny flowers look like miniature snapdragons.

For the impatient gardener, Mazus reptans fills in quickly, but is well-behaved. It hugs the ground to form a tight carpet. In spring, tiny snapdragon-like blooms give the effect of a miniature flower garden. Blue or white with yellow markings, the blossoms rise up 2 to 4 inches above the foliage. Its many fibrous roots make it easy to propagate by division. Use this hardy perennial where its aggressive qualities can be appreciated, such as between stepping stones or to cover large patches of soil. For an alluring combination, plant Mazus reptans along the edge of a pond with cardinal flower (Lobelia cardinalis).

Other ground covers show off best in the shade

If you’re looking for a rugged plant that will thrive even in boggy areas, try golden creeping Jenny (Lysimachia nummularia ‘Aurea’). Also known as gold moneywort, this moisture lover puts out roots all along its stems so that large areas of ground are covered very quickly. Although the species is an aggressive grower in some areas, I’ve found that this cultivar is more wellbehaved. Even so, you may want to curb its growth by creating barriers.

Golden creeping Jenny is also a good creeper to choke out weeds. Its shiny, rounded, yellow-green leaves light up an area and contrast well with dark-colored herbaceous plants like Arum italicum ‘Pictum’ and ‘Palace Purple’ alum root (Heuchera micrantha var. diversifolia ‘Palace Purple’).

More of a leaper than a creeper, ‘Eco-Lacquered Spider’ green-and-gold (Chrysogonum virginianum ‘Eco-Lacquered Spider’) is an outstanding new selection of this native species. It stands out with rosettes of blue-green, metallic-looking leaves, and small, daisylike flowers about an inch in diameter. In winter, the foliage takes on tinges of purple. A fast grower, a one-gallon plant will cover an area five times as large in a single growing season. It sends out long, above-ground stolons that touch down and take root. For a stunning combination, plant ‘Eco-Lacquered Spider’ green-and-gold next to the charming, native dwarf crested iris (Iris cristata), which blooms around the same time.

Another fine candidate for the woodland is peacock moss (Selaginella uncinata). With its tiny, fernlike, aquamarine-blue leaves, this plant looks almost prehistoric to me. Vigorous but not invasive, peacock moss forms tight mats of foliage that reach only 4 to 6 inches tall. This semi-evergreen perennial grows happily in combination with hellebores and ferns.

It’s easy to get ground covers growing

Ground-cover plantings are relatively easy to establish, whether you use seedlings, divisions, or rooted cuttings. Once you select an area to plant, prepare the soil in advance.

Since all the plants described in this article spread rather quickly, plant 2- to 3-inch seedlings or divisions on 6-inch centers. Apply a light layer of mulch to retain moisture and discourage weeds. Water new plantings daily until they become established, and then water according to the plant’s moisture needs.

‘ECO-LACQUERED SPIDER’ GREEN-AND-GOLD
Botanical name: Chrysogonum virginianum ‘Eco-Lacquered Spider’
Range: Zones 5 to 8
Culture: While it’s happiest in dappled shade, such as along woodland edges, it will also adapt to sunnier spots if it’s watered during periods of drought. Plant divisions or rooted stem cuttings in the spring. In warmer climates, you can also plant in the fall.

GOLDEN CREEPING JENNY
Botanical name: Lysimachia nummularia ‘Aurea’
Range: Zones 4 to 8
Culture: This moisture lover also adapts to dry soil. To encourage the brightest foliage, site this prostrate perennial where it gets morning sun but is shaded during the hottest part of the day. Plant divisions or rooted cuttings any time during the growing season.

GOLDEN OREGANO
Botanical name: Origanum vulgare ‘Aureum’
Range: Zones 5 to 9
Culture: Give this spreader lots of sun and good drainage. Plant divisions or rooted cuttings in the spring.

GOLDEN CREEPING THYME
Botanical name: Thymus X citriodorus ‘Aureus’
Range: Zones 6 to 9
Culture: Native to the Mediterranean, it grows best in full sun and will endure only in well-drained soil. Amend average soil with sharp sand or course gravel to ensure good drainage. Plant divisions or rooted cuttings in the spring. Regular shearing improves air circulation and reduces fungal problems. Even when small sections of this ground cover die out, it bounces back quickly.

MAZUS REPTANS
Botanical name: Mazus reptans
Range: Zones 5 to 8
Culture: Plant it in shade for the best performance, but it also grows well in full sun as long as it’s in moist soil. Plant divisions any time in the growing season or rooted cuttings in the spring.

PEACOCK MOSS
Botanical name: Selaginella uncinata
Range: Zones 7 to 11
Culture: Grow in moist woodland soil. Transplant pieces of stems where roots have formed any time in the growing season, or plant divisions in the spring. If the frondlike tips dry out or die back in winter, simply cut them back in early spring to expose the colorful new growth.
