外形から見ればラッパズイセンと命名されて妥当ですが、ラッパという音の響きはこの花にふさわしくないと思います。これは、単なる私の好みです。
The trumpet daffodil is called "ラッパズイセン: rappa zuizen" in Japanese.
"Rappa" is the generic name of the brass instrument in Japanese.
Judging from the external form, it is proper to name this flower "rappa".
But I think that the sound is not suitable to this flower.
This is my merely preference.
