Description
C. aromaticum is a perennial graminoid of the Poaceae family native to North America. [1] The whole plant is aromatic, which is what the specific epithet is named after. Sterile individuals can be identified by the broad and bicolored leaves that are bluish on the upper side and bright green on the under side.[2] The plant as a whole reaches heights between 2 and 3 feet, with leaf blades 6 to 10 inches long. Seedhead is a spike that is curved with sessile spikelets on one side of rachis, which gives it the appearance of a comb.[3]
Distribution
C. aromaticum can be found in the southeastern part of the United States, specifically in Florida, Georgia, Alabama, Mississippi, Louisiana, South Carolina, North Carolina, and Virginia. [1] It is an endemic species of the Southeastern Coastal Plain.[2]
Ecology
Habitat
Ideal habitats for the C. aromaticum are in moist clay that may have some standing water after heavy rains. It has adapted to extremely wet conditions with acidic soils. [1] C. aromaticum is considered an indicator species in the upper Florida Panhandle wetland regions. It is also a dominant grass in lower panhandle savannas. [4] Specimens have been collected from habitats including longleaf pineland, wet loamy sands near bog, recently burned pineland, wiregrass savannas, flatwoods savannas, ponds, and prairies. [5] As well, this species is listed as a facultative wetland species, where it grows mostly in wetlands but can also be found in non-wetland areas.[1]
Phenology
C. aromaticum flowers periodically between June and August, but can flower later in response to fires in the late summer.[2] However, it has been seen to flower earlier in the year, a few months after a prescribed burn. Edwin Bridges observed a region starting to flower in February after a prescribed fire in November in a pine savanna. .[6]
Seed bank and germination
Seed germination starts in Map and June that develop into stalks that produce plentiful seeds. [1]
Fire ecology
Seeds are produced after the region has been burned.[1] It is known to only flower generally in response to fire.[2]
Use by animals
This grass can be used for livestock to graze on.[3] The seeds are one of the preferred species by the Henslow's Sparrow for food in the winter. This species had long been considered an indicator species of Henslow's Sparrow habitats. [7] The entire plant if chewed by humans causes numbness to the mouth, tongue, and lips.[2]
