People spend their money and time on many things that are not essential to them staying alive. They are whatever takes their fancy - usually either for status or a "reward" that gives them a feeling of pleasure. The fashion and entertainment industries are just about 100% driven by that motivation.
Having a flower garden is a discretionary spend. Employing a gardener is therefore one further expense of doing that. Adding some entertainment novelty is just another apparently unnecessary expense that they want to afford.
