Anytime people want to express love, they use symbols like heart, flower, etc which means God didn't make a mistake when He gave Adam his first job as a gardener; to make the garden beautiful, and later tasked husbands to love their wives.
Taking care of a garden requires lots of hard work, taking its beauty into consideration by constant watering, clearing of weeds, pruning, etc. The man was trained to learn how to bring out the beauty in things and it was no accident when he was given a beautiful woman as a wife and then asked to love and make her more beautiful.
