The word “yields” can be interpreted as a verb, which speaks back to the concept that he and his lover are going to “prove.” In this way, the speaker is proposing to his lover that she come live with him so that they can prove all these natural items will yield, or result in, pleasure. In other words, he says they will experience all the joys that nature has to offer.
