noun
lychnis; Lychnis senno
A flowering plant in the carnation family, native to Japan and East Asia. The name refers specifically to Lychnis senno, a perennial with bright pink or red flowers. Used in gardening and traditional contexts.
仙翁は夏に鮮やかな花を咲かせる。
Lychnis senno blooms with vivid flowers in summer.
庭にセンノウを植えてみた。
I planted some lychnis in the garden.
Refers to the same plant, but 仙翁花 (センノウゲ) is a longer, more descriptive name. 仙翁 is the standard shorter form.
The name 仙翁 (せんのう) is of Japanese origin, likely derived from the plant's appearance or traditional associations. The exact derivation is uncertain; it may refer to a legendary hermit (仙翁) due to the plant's elegant, long-lived nature.
