10 Seeds Ferula communis Giant Fennel Ornamental Architectural

Ferula communis, commonly known as Giant Fennel, is a striking herbaceous perennial prized for its bold architectural form. It produces deeply divided, feathery green foliage and, in time, tall stout stems topped with large umbels of tiny yellow flowers, creating a dramatic vertical accent in borders and wilder garden settings.
Ideal for adding height and texture to ornamental plantings, Mediterranean-style gardens, and meadow schemes. The airy flower heads offer visual interest through summer and can be left standing for winter structure. Seeds are best sown in a free-draining medium and given a period of cool stratification to support reliable germination.
