Wikipedia 설명

 

Helenium autumnale is a North American species of poisonous[3] flowering plants in the family Asteraceae. Common names include common sneezeweed and large-flowered sneezeweed.[4][5][6]

Description

Common sneezeweed is a perennial herb up to 130 cm (51+1⁄3 in; 4+1⁄3 ft) tall. In late summer and fall, one plant can produce as many as 100 yellow flower heads in a branching array. Each head has yellow 11–21 ray florets surrounding sometimes as many as 800 yellow disc florets.[7][8] Leaves are dark green, alternate, and lance-shaped. The Latin specific epithet autumnale is in reference to the plant's autumn flowering.[9]
