type of wisteria
萪 refers to a specific type of wisteria, a climbing plant known for its cascading flowers.
萪 combines the grass radical 艹 with 科, which likely provides the sound カ. The character was created to name a specific plant, a type of wisteria.
The grass radical 艹 sits above 科, like a wisteria vine climbing over a measuring rod (科 can suggest a category or measure). Picture the plant being classified as a type of wisteria.
For カ, imagine a car (カ) driving under a wisteria trellis, the flowers brushing the roof: car -> カ.
