ABSTRACT
The number of flowers or branches to be arranged in a vase varies from two to eight or nine, i according to the size of the vase and the nature of the flowers or branches. One branch may sometimes be sufficient, but usually a single branch or flower makes too simple an arrangement to be satisfying, since it is obvious, for instance, that the situation becomes geometrically complicated by the simple mathematical addition of one branch, say C, to the two already arranged branches A and B. So at least two or three branches should be used.
