Description

Grassleaf Barbara's Buttons is a native, flowering perennial wildflower found in moist to wet flatwoods, pine savannas, pocosins, and bogs in the Coastal Plains of the Southeastern United States, extending as far west as Texas, and belongs to the daisy family (Asteraceae). In the late summer and early fall, Grassleaf Barbara's Buttons produces showy, sweetly fragrant, white to pale pink blooms of tubular disc florets above its bright green, long, grass-like leaves. The rest of the year, its rosette of low-growing green foliage can provide foreground accents for other blooms. The genus name Marshallia honors an American botanist, Moses Marshall. The specific epithet graminifolia means "grasslike leaves"; hence the common name.

Prefers full sun to partial shade and moist to wet, organic, acidic soils. It is hardy in zones 7a to 10b. They grow best in coastal or piedmont regions. It is wet-soil tolerant. Propagated best by seeds or division.

Consider for use in a wildflower garden or water garden, or near a pond or bog. This native wildflower is available at nurseries specializing in native plants. The flowers attract pollinators, and the long-lasting blooms are a good choice as a cut flower.

Insects, Diseases, and Other Plant Problems:  No known serious insect pests or diseases. Monitor for aphids and slugs. Provide good circulation to prevent fungal diseases.
