The Vietnamese word "bách thảo" refers to "all plants as a whole" or more specifically a "botanical garden." It’s a term that encompasses the idea of a place where various types of plants are cultivated and displayed for educational, scientific, and aesthetic purposes.
While "bách thảo" primarily refers to botanical gardens or plants in general, context can sometimes shift its meaning. In more poetic or literary contexts, it might evoke images of lush greenery or the beauty of nature.
