Foeniculum vulgare ‘Purpureum’, also known as Bronze Fennel, is a strongly aromatic flowering perennial that is known as an ornamental as much as it is a culinary herb. Finely textured, feathery, fragrant foliage emerges purple and later becomes gray-green, followed by upright umbels of yellow flowers from June to July. The yellow blooms contrast beautifully with the purple foliage in the naturalistic or herb garden amongst other mid-summer flowering perennials. If spent flowers are not deadheaded, they will become aromatic, anise-scented seedheads, which will later self-seed in the garden. Fennel is a host plant for Swallowtail Butterfly larvae.
