Carex comosa is a species of sedge known as longhair sedge and bristly sedge. It is native to North America, where it grows in western and eastern regions of Canada and the United States, and parts of Mexico.[1] It grows in wet places, including meadows and many types of wetlands.[2] Tolerates deeper water than most common species and is good for retention basins. This sedge produces clumps of triangular stems up to 100 or 120 centimeters tall from short rhizomes.[3] The inflorescence is up to 35 centimeters long and has a long bract which is longer than the spikes. It is a cluster of several cylindrical spikes. The scales over the fruits taper into long, thin awns.[4] 先生✨ などと出ました。いかがでしょうか？
虫みたいに見えますが、植物です。
わからなかった名前が判明しました。Carex bristly sedge(カレックスブリストリーセッジ)又はcarex comosaというスゲ属の日本にもあるカヤツリグサの仲間でした。天美ちゃんさん、kaorinさん、＊Chie＊さん、ひまさん、しぃさん一緒に考えてくださって、コメント回答ありがとうございました😊
