Great Design Plant: White Prairie Clover (Dalea candida) for Pollinators and Soil Health

For a beautiful, beneficial, underused native, consider white prairie clover (Dalea candida) for next year's planting. A sibling to purple prairie clover (D. purpurea), it blooms a week or two earlier—delivering a summer one-two punch for pollinators. Larger, longer leaves distinguish it out of bloom. This central U.S. native thrives in drought and varied soils where others fail.

• Light: Full sun
• Mature size: 1–2 feet tall and wide
• Benefits: Adaptable, resilient; various soils; pollinator magnet; nitrogen-fixing
• Seasonal interest: Early to late summer bloom (region-dependent); ornamental autumn seed heads attract wildlife

Distinguishing Traits

Airy, open form with stems radiating from a central crown. Lacy, deeply lobed leaves. Blooms progress bottom-to-top over 1–2 weeks. Flowers draw diverse pollinators—native bees, flies, moths. Host plant for Reakirt's blue (Hemiargus isola) and southern dogface (Zerene cesonia) butterflies. Autumn seeds feed birds and small mammals, striking against blue skies.

Landscape Uses

• Drought-tolerant moon garden (white/silver blooms)
• Massed with short native grasses: little bluestem (Schizachyrium scoparium), sideoats grama (Bouteloua curtipendula), prairie dropseed (Sporobolus heterolepis)
• Paired with purple prairie clover (blooms as D. candida fades)
• Indicator of healthy, established prairie—absent from disturbed sites

Ethnobotany: Several Native American tribes brewed leaf tea, chewed roots, used dried stems as brooms.

Planting Notes

Thrives in clay, loam, sand, rocky soils. As a legume, it fixes nitrogen—free fertilizer for neighbors. Plant in groups among perennials. Critical: Needs full, hot sun—don't let taller plants shade it out.
