秋桜(コスモス) cosmos

　コスモスは秋の桜と書きますが、花は桜というより菊ににています。秋菊と名付けた方が良いように思いますが、秋菊（シュウキク）は、菊の別称、つまり菊そのものなので、使えませんね。

　Cosmos is written as autumn cherry blossoms, in Japanese, but the flower looks more like chrysanthemums than cherry blossoms. In my view, it would be more appropriate to call it autumn chrysanthemum, but since autumn chrysanthemum is another name for chrysanthemum, in other words, chrysanthemum itself, so you cannot utilize it.
