Giant Fennel shouldn't be confused with the culinary Fennel, Foeniculum. These vigorous-growing perennials are found wild in rough, rocky ground of the Mediterranean region. These plants are mainly grown for their interesting and attractive feathery foliage.It grows 6 to7 feet high with a spread of 2 or 3 feet. Its rich green leaves are large and finely cut into very thin, linear sections. The tiny, yellow flowers are produced in rounded umbels on long, stout, branched stalks, from late spring to summer.These plants might die after blooming. They are very pretty planted in the wild garden or by the side of a pond. .
