Hog's-fennel is a tall, hardy perennial of the carrot family, native to rough grassland and sea-side clay banks in Central and Southern Europe. It is rare in the UK and is not a common garden plant, so it suits wild or naturalistic planting in sunny, well-drained spots.

Where it grows

Rough grassland, clayey banks and cliffs near the sea. It is a glabrous perennial with stems up to 2 m in height, solid, striate, sometimes weakly angled, sparsely blotched wine red, surrounded by fibrous remains of petioles at the base and springing from a stout rootstock. The umbels of greenish-yellow flowers contrast pleasingly with the bushy, radiating mass of dark green, long-petioled leaves, which bear linear, sessile lobes, attenuate at both ends and having narrow, cartilaginous margins (i.e., individual lobes resembling blades of grass).
