Produces clouds of feathery bronze/purple leaves contrasting with tall, sulphur yellow flower heads. It is well suited to growing among ornamental grasses and tall perennials in a wild prairie style planting scheme. The tall foliage can be used effectively to create a semi translucent screen for viewing other planting through.

Fennel is grown for it’s ferny foliage as well as it’s tall yellow flowers. If flowers are allowed to seed fennel will self seed but can be held in check by removing the flower heads. Fennel provides a valuable Winter habitat for insects so should not be cut back until March.
Provides pollen and nectar for smaller pollinating insects including solitary bees, hoverflies, soldier beetles, damsel bugs, flower bugs, shield bugs and mini braconid wasps (beneficial predators to caterpillars and aphids). Also provides a Winter home in holly stems for hibernating insects and their larvae.
