Piedmont Barbara's Buttons

Marshallia obovata (mar-SHALL-ee-uh ob-oh-VAY-tuh)

Family: Asteraceae Native Herbaceous

Piedmont Barbara's Buttons is a flowering herbaceous perennial in the Aster family. This clump-forming plant with flowering stems and basal leaves appears in spring and can reach up to 2 feet tall at maturity. The plant is native to the southeastern piedmont of North Carolina and is usually found in open woodlands and along roadsides throughout the southeast. Piedmont Barbara's Buttons does best in evenly moist to dry, well-drained soils in full sun to part shade. It will tolerate some drought once established and most soil types as long as they are well draining. It will self sow in ideal conditions. This plant was selected as the 2009 NC Wildflower of the Year , a program managed by the North Carolina Botanical Garden with some financial support from the Garden Club of North Carolina. It is good for rock gardens and in the front of beds. Diseases, Insect Pests, and Other Plant Problems No known diseases or insect pests.
