Foeniculum vulgare ‘Smokey Bronze’
‘Smokey Bronze’ Fennel is a striking ornamental herb prized for its feathery copper-bronze foliage and sweet anise fragrance. Growing 4–6 feet tall, this dramatic plant adds height, texture, and color to herb gardens, perennial borders, and pollinator plantings.
In summer, delicate golden-yellow flower clusters appear above the airy foliage, attracting bees, butterflies, and beneficial insects—including the beautiful black swallowtail butterfly, whose caterpillars often feed on fennel leaves.
‘Smokey Bronze’ thrives in full sun and well-drained soil, producing its richest color with plenty of sunlight. Young plants appreciate consistent moisture, but once established they are fairly drought tolerant and easy to grow.
Both the aromatic foliage and seeds are edible, offering a mild licorice flavor that can be used in salads, teas, and cooking.
