Generally when buying flowers the first thing to mind is not necessarily, should I choose a bouquet or arrangement? It's more about how you want your recipient to feel.... There are a few reasons why a flower arrangement can be a good choice. Firstly, a flower arrangement is simply a beautiful set of flowers arranged in a container or vase, so that it can hold water and stand on its own. This makes it easier to receive flowers as the recipient does not need to worry about finding a suitable container or getting the flowers into water in a hurry!
