noun
A coastal variety of daylily (Hemerocallis fulva var. littorea) with orange flowers, found on sandy shores in Japan.
海岸にハマカンゾウが咲いていた。
Orange daylilies were blooming on the seashore.
The name ハマカンゾウ (浜萱草) literally means 'beach daylily', from 浜 (hama, 'beach') and 萱草 (kanzō, 'daylily'). The derivation is straightforward from its coastal habitat.
