Although pollinator populations are diminishing worldwide due to habitat loss, climate change, pesticides, and disease, gardeners can slow this decline through cultivating and maintaining safe environments where winged garden visitors can find sustenance and take shelter. Combining well-chosen trees, shrubs, perennials, and vines to create a varied habitat will attract and support a broad range of bird, mammal, and insect species. Incorporating a strategic array of ground covers into this mix is a great way to maximize the wildlife benefits your garden offers.

Lawns are green deserts for wildlife, and areas that are mulched with bark, pine needles, or gravel offer little habitat and no food for beneficial insects and other creatures. In the wild, bare soil hardly exists; it is always covered with plants. Then why do we leave so much exposed soil in our gardens? Most gardens offer many opportunities to layer ground covers beneath and between perennials, shrubs, and trees, adding beauty and multiseason interest. Look for nooks and crannies in pathways, along border edges, in walls, and along stairways where pockets of bare soil could be filled with ground covers. Trailers that drape over the edges of hardscaping and container plantings add fun, whimsy, and a sense of completeness to your designs. Add the right ground covers and the pollinators will thank you.

Choose the best ground covers for your garden

With thousands of ground covers to choose from, which ones will be best for your pollinators? One helpful strategy is to select ground covers that offer a succession of blooms from early spring until fall. While some pollinators are active through much of the growing season, others may live for just a few weeks. Including long-blooming varieties ensures that there will be a bounty of nectar and pollen from the time the snow melts in spring to when your garden freezes again the following winter. It is best to select plants that have flowers with a diverse array of sizes, shapes, and colors. Each pollinator species seeks out particular bloom sizes and shapes. For exam­ple, hummingbirds appreciate large, tubular flowers, while butterflies need smaller tubular flowers and a place to rest while feeding. Native bees of various sizes also need a range of flower types from which to feed. The greater the diversity of flower shapes, sizes, and colors, the more pollinators you will attract.

It is also ecologically beneficial to choose ground covers with a variety of foliage textures and with different growth habits, including rhizomatous, suckering, stoloniferous, spreading, and trailing. Covering the ground with diverse plantings will support insects that are food sources for songbirds, frogs, toads, snakes, and mammals. It will also encourage a richer biome of healthy soil bacteria and fungi that support overall plant health.

Including native plants is a guaranteed way to attract and support local pollinators that have co-evolved with these species and that seek out the protein and fats provided by pollen and the sugary nectar they need for energy. Native plants are also often the only larval hosts for native butterfly and moth species. However, since not all our natives have long bloom periods, and since our small gardens can’t compensate for the loss of natural habitat to urban and agricultural development, nonnative plants can be used to fill gaps in nectar and pollen supply. The following are some of the many fine ground covers that you can incorporate into garden designs to add beauty and provide the greatest pollinator benefits per square foot.

 

Spring Flowers Sustain Emerging Pollinators

Virginia strawberry spreads sweetly around taller plants

Name: Fragaria virginiana

Zones: 3–9

Size: 3 to 9 inches tall and 12 to 24 inches wide

Conditions: Full sun to partial shade; rich to average, well-drained soil

Native range: North America

Pollinator power: Attracts a variety of native bees and hoverflies; nectar source and larval host for dozens of butterfly and moth species

This tough, vigorous, easy-to-grow ground cover is also a powerhouse for pollinators. The white, five-petaled flowers provide nectar and pollen for early foragers from spring to early summer, and the small, tasty fruits that follow will delight chipmunks, squirrels, birds, and humans alike from early to mid­summer. Use it under and around taller plants, as a lawn substitute, or as a slope stabilizer. In good conditions it will spread almost indefinitely. While the plants grow and spread quickly, it may take time for the rosettes to provide a closed cover. Virginia strawberry will tolerate occasional foot traffic and is deer- and rabbit-resistant. The plants appreciate evenly moist soil but will tolerate short periods of drought.

 

Rock soapwort is a small, fragrant powerhouse

Name: Saponaria ocymoides

Zones: 3–8

Size: 4 to 8 inches tall and 12 to 24 inches wide

Conditions: Full sun; average to dry, well-drained soil

Native range: Sunny slopes and rocky areas from Spain into the Alps

Pollinator power: Attracts bees, butterflies, and possibly hummingbirds

Here is an extremely hardy, old-fashioned perennial that forms compact carpets of vigorous, semi-evergreen foliage. In late spring and summer, the densely branched plants are topped with prolific clusters of small, fragrant flowers that can be bright pink to white, depending on the cultivar. Plant it in average to poor soil with good winter drainage; you will find that it is quite tolerant of drought. It is perfect for small to medium-size areas in rock gardens, between stepping stones, along pathways, on slopes, and atop walls. Rock soapwort is deer resistant and tolerates occasional foot traffic.

 

Roundleaf groundsel furnishes pollen, nectar, and spring cheer

Name: Packera obovata

Zones: 3–8

Size: 12 to 20 inches tall and 6 to 12 inches wide

Conditions: Full sun to partial shade; dry to wet soil

Native range: Eastern North America

Pollinator power: Attracts many species of native bees, hoverflies, and beetles; larval host to the northern metalmark butterfly

Roundleaf groundsel greets spring with cheerful yellow flowers that seem to float above mats of basal foliage. It is adaptable to a variety of sun and soil conditions, making it useful for repeated plantings that visually connect different areas of the garden. Its flexibility and quick growth rate make it an ideal candidate anywhere a tough, easy-to-grow, weed-suppressing ground cover is needed. It spreads by both stolons and rhizomes to form dense mats of rounded, semi-evergreen leaves that are 4 to 6 inches tall. The flat-topped clusters of golden yellow, daisylike flowers rise on nearly leafless stems that are 10 to 20 inches tall. Plant roundleaf groundsel en masse under trees and large shrubs, beside water features, along pathways, in borders, in woodlands, and on slopes for erosion control. It is deer resistant.

‘Honey Coral’ trumpet honeysuckle tempts hummingbirds, butterflies, and bees

Name: Lonicera sempervirens ‘Honey Coral’

Zones: 4–9

Size: 8 to 24 inches tall and 10 to 15 feet wide (without support)

Conditions: Full sun to partial shade; rich, moist, well-drained soil

Native range: Eastern North America

Pollinator power: Attracts hummingbirds, butterflies, and bees; larval host for several moth and butterfly species

Trumpet honeysuckle is a native vine beloved for its bright red but sometimes yellow flowers that bloom in mid to late spring and intermittently throughout summer. ‘Honey Coral’ is a valuable compact form of the species. Though this vigorous, twining vine can grow 10 to 15 feet tall or more if it is trellised, in the absence of vertical structures it can perform well as a large, rambling ground cover. Use it on slopes and banks or to cover open areas, uneven ground, and unsightly landscape features such as rocks or stumps. Its tube-shaped flowers are appealing to many pollinators, and its red berries are attractive to birds in autumn. ‘Honey Coral’ is tolerant of drought and resistant to deer and rabbits.

 

‘Poncha Pass Red’ sulphur buckwheat is colorful over a long season

Name: Eriogonum umbellatum ‘Poncha Pass Red’

Zones: 3–8
