"It is her birthday tomorrow. I want to give her flowers."

Translation: 明天是她的生日，我想送花给她。

So would I be right in saying the literal translation of the second phrase would be: "I want to give (送) flowers to (给) her" ？ ...我想给她送花 was also accepted.

送 means "to send without any payment", whereas 给 means "to give".

So your answer also matches the meaning and context of the sentence.

Actually , there's a special construstion "送+给+谁"。So,it can be used only like , not the wat it is presented in the example
