It seems from what I have read, that the smell of Fennel, Foeniculum vulgare (hence the pun!) is one of those you either love or hate. I therefore consider myself lucky at the moment because the acid yellow umbelliferous flowers have given way to thousands of seeds which are now ripening on the huge clump by the back gate and there is the most gorgeous smell of licorice / aniseed as we brush past it each morning to take the dogs for a walk.
The tall feathery foliage on thick branching stems makes a bold architectural statement in any garden. It loves a well drained poor soil in full sun and, unfortunately for some, seeds itself freely around the garden. I think the smell takes me back to my childhood eating Bassett’s Licorice Allsorts and aniseed balls!
