영어 위키 설명

 

Chasmanthium latifolium, known as woodoats, inland sea oats, northern sea oats, and river oats is a grass native to the central and eastern United States, Manitoba, and northeastern Mexico; it grows as far north as Pennsylvania and Michigan, where it is a threatened species. The species was previously classified as Uniola latifolia (André Michaux).

 

Description​

Chasmanthium latifolium is a cool-season, rhizomatous perennial grass with stems about 1 m [3 feet] tall. The plant typically grows in wooded areas and riparian zones.

 

Gardens

It is used in landscaping in North America, where it is noted as a relatively rare native grass that thrives in partial shade; the plant is recommended for USDA hardiness zones 3–9 in acidic sands, loams, and clays.

Noteworthy Characteristics

Chasmanthium latifolium, a clump-forming, upright, ornamental grass, is a Missouri native plant which typically grows 2-5' and most often occurs in rich woods or rocky slopes along streams and on moist bluffs. This grass is perhaps most distinguished by the flat, drooping seed heads which hang in terminal clusters on thread-like pedicils from slightly arching stems. Seed heads will flutter when caressed by even the softest of breezes. Seed heads emerge green but turn purplish bronze by late summer. Bright green leaves (5-9" long) turn a coppery color after frost and eventually brown by winter. Excellent for dried flower arrangements. Common name of inland sea oats is in reference to the similarity of the seed heads to those of oats. This grass was once known as Uniola latifolia.

 

Genus name comes from the Greek chasme meaning gaping and anthemum meaning flower for the form of the flower.

 

Specific epithet means broad-leaved.

낚시귀리와  Bromus briziformis 차이

 

인터넷을 아무리 검색해도 두 종의 차이를 명시한 곳은 찾을 수 없지만  검색한 사진으로 보다면 Bromus briziflormis는 대체로 호영에 짧은 까락이 있고 낚시귀리(Chasmanthium latifolium)는 까락이 없는 것으로 보인다.  Bromus briziflormis는  잎이 좁고 엽초에 개출모가 있는 대신 낚시귀리(Chasmanthium latifolium)는 잎이 넓고 엽초에 털이 없는 것으로 보인다.
