day lily
萓 refers specifically to the day lily, a flowering plant. Its meaning is narrow and botanical, without broader abstract extensions.
萓 combines the grass radical 艹 with 宜, which likely contributes a phonetic element. The character was created to name the day lily plant.
The grass radical 艹 sits above 宜, like a lily blooming on top of a sturdy stem. Think of a day lily rising from the grass.
For ギ, imagine a day lily with a giant, gear-shaped bloom: gear -> ギ, and the flower turns like a gear in the sun.
