plant sale text: A moist to wet-sited cousin of Piedmont Barbara's Button (Marshallia obovata var. obovata), Grass-leaf Barbara's-buttons is found growing in wet pine barrens and low lying moist areas of the Coastal Plain from NC to FL. The majority of the year, this semi-evergreen species exists as a low growing rosette perfect for the foreground of a moist sunny perennial bed. Beginning in July, Grass-leaf Barbara's-buttons forms tall, sparingly branched stems topped by sweetly fragrant, 1" wide ball-shaped flower heads. This composite is made up of all disc flowers (there are no ray flowers). This species is also a great nectar source for several butterfly species.
