HORTICULTURAL
Plant Sale Text: Native to the nutrient-poor soils of the Coastal Plain, toothache grass is rather non-descript until it flowers and sets seed. As the seed heads dry, they curl up and are very unusual and extremely ornamental. As the common name implies, parts of this plant (namely the roots) have a numbing effect when chewed.

WEAKLEY FLORA

SCIENTIFIC NAME: Ctenium aromaticum
COMMON NAME: Toothache Grass, Orange Grass
SYNONYMY: [= C, F, FNA, G, GW, HC, K, RAB, Va, WH3; = Campulosus aromaticus (Walter) Trinius - S]
PHENOLOGY: Jun-Aug (or later in response to late summer fires).
HABITAT: Wet savannas, pocosin-savanna ecotones, seepage bogs, sandhill-pocosin ecotones, sandhill seeps.
COMMENTS: Southeastern Coastal Plain endemic: se. VA south to FL and west to LA and e. TX (Singhurst, Keith, & Holmes 2005). The entire plant is aromatic and numbs the mouth, tongue, and lips when chewed, hence the specific epithet and common names. Like many species of the longleaf pine ecosystem, toothache grass generally flowers only following fire (MacRoberts & MacRoberts 1992). Sterile clumps can be recognized by the rather broad, bicolored leaves (bluish on the upper surface, bright green on the lower surface).
