Since both the word "botanic" and "garden" refer to plants, wouldn't the phrase "botanical garden" a redundant words?

You're right that they both refer to plants! However, the phrase "botanical garden" refers to a garden made for public display or studying. You can use the word "garden" in different ways. The phrase "vegetable garden" refers to a garden that grows vegetables. There are many types of gardens with specific functions. The name can also change depending on what is grown in the garden. Ex: I'm going to get some vegetables from the garden! Ex: Would you like to come to the botanical gardens with me? Ex: Did you see the rose garden at the hotel? It was beautiful.
