Line flowersstand tall and have many blossoms close to the stem. They are “showy” flowers like liatris, snap dragons, delphiniums, stock, gladiola and Canterbury bells. The line flowers are inserted both vertically and horizontally in the design first, to establish the direction and shape of the arrangement. Focal and filler flowers are added to add to the shape and feeling of the design.

Focal flowers, like roses, magnolias, hydrangeas and peonies are single stem, compact the flowers that command the attention of the viewer. They are placed close to the center of the arrangement slightly above and drooping below the edge. They add stability to a design.
