HORTICULTURAL
Plant Sale Text: The seed heads of this native grass add great ornamental appeal in the fall, when its upright open panicles appear. The overall effect is of a fluffy rose-colored cloud. The narrow leaves of Hairgrass keep a low, tufted profile for the rest of the growing season. Every autumn, this is one of the most admired plants in the perennial borders at the North Carolina Botanical Garden. Many visitors comment on its unusual beauty in the fall.

WEAKLEY FLORA

SCIENTIFIC NAME: Muhlenbergia capillaris
COMMON NAME: Hairgrass
SYNONYMY: [= F, FNA, G, K2, Pa, Va, W, Y; < M. capillaris - GW, RAB; = M. capillaris var. capillaris - C, HC, K1, S, WH3, Z]
PHENOLOGY: Late Aug-Oct.
HABITAT: In the Piedmont and Interior Low Plateau primarily in clayey or thin rocky soils (especially in areas which formerly burned and were prairie-like) and in open woodlands, in the Coastal Plain in savannas, dry woodlands, and coastal grasslands (where sometimes in close proximity with M. sericea), in the Mountains around calcareous rock outcrops.
COMMENTS: MA, NY, s. OH, s. IN, s. IL, MO, and e. KS south to s. FL, LA, and s. TX. M. capillaris and its relatives, M. expansa and M. sericea, have been the subject of an herbarium morphological study by Morden & Hatch (1989), who conclude that the three taxa are not sharply separable and should be recognized only at the varietal level. If one considers behavior in the field, ecology, and geography in conjunction with morphologic characters, however, there is little doubt that the three taxa are biological species. Distribution and typical habitat are different for the three species, but M. capillaris can be found growing with or in proximity to each of the other two (I have not seen M. sericea and M. expansa together). In such situations, the two taxa present are readily distinguishable at a glance, and there is no evidence of intermediates or hybrids. Gustafson & Peterson (2007) also concluded that the three taxa are separable as species.
