Design a dome
When using a wide container, add water-soaked floral foam to keep blooms in place. Michael recommends leaving about an inch of foam above the container’s rim. Snip stems short. Insert them into the sides and then the top of foam. “This will let you create a full dome of flowers,” he says. Giant red zinnias pop against pale chartreuse zinnias, wispy celosias and lemon basil leaves in this low ceramic bowl for a sweet summer blend.
