By mid-August, simple flower arrangements are a relief from the intensity of the garden. The flowers of summer - sunflowers, hydrangeas, lilies, dahlias - are such showboats that they dominate any arrangement, so it's best to showcase a single flower, or a couple of very similar tone-on-tone flowers and foliage. As summer winds down, anything overdone looks too fussy and fevered.
A simple tone-on-tone arrangement celebrates the deep golden, daisy-like flowers of high summer. The ligularia petals look as if they're being blown about in the wind, lending swirl and motion, while the puffy dark brown centers on the Helenium autumnale anchor the bunch. The deep sea blue/green color, and the bulgy base of the mottled metal vase lends solidity to the haze of gold petals.
