The true beauty of a flower is seen where it is in its natural state on the plant, in the middle of nature - maybe a garden or in the wild. A beautiful bouquet sometimes brings that beauty artificially closer to us and in our homes or desks. But a bouquet ultimately results in the unnatural death of a flower as it withers and shrivels. It smells different once it withers. In nature it loves beautifully and fades away with dignity before dropping on to the ground where it creates a beautiful carpet.
This picture of a 'pretty' bouquet shows that the flower is withering away painfully. Devoid of its natural home, it still adds a touch of beauty - but nowhere close to its beauty in nature.
