The bogbean blooms beautifully in the marshes during spring.
Bogbean is formed from "bog" (from Old English *boc*, meaning a wet, marshy area) and "bean" (from Old English *bean*, meaning a bean or leguminous plant). The word refers to a plant that grows in wet, marshy areas, resembling beans.
Think of a 'wet area' ('bog') where a 'bean-like plant' ('bean') grows — that's what bogbean refers to.
