Somewhere, probably in a gardening magazine, I got the idea of using dill and fennel blossoms in bouquets. This is the first year that I have grown fennel. With a slightly greener yellow in the bloom, fennel seems stubbier and sturdier than dill.
Both are classified as simple umbels, a botanical designation for a flower head that forms a dome or or disc shape, and that branches only once before producing flowers.
This bouquet uses fennel and large marigolds together. The soft yellow lacy fennel contrasts with the dark green foliage and orange blossom of the marigold. It's an unlikely combination for a late summer bouquet.
