As with the anemone, I also made a simple arrangement of all-purple hydrangea. With grouping posies of different heights, the key in the arranging is to stagger the heights so that you can see all of the flowers, without making a stiff tower of blooms. When a flower has a face, such as with the anemones, you can position the faces such that there is a sense of movement and connection among them; with a flower like hydrangea, nestle the stems tight against each other to create one lovely mass.
