About Hogweed
Heracleum sphondylium, commonly known as hogweed or common hogweed, is a perennial herbaceous plant belonging to the Apiaceae family, native to Europe and Asia. It is characterized by its large lobed leaves and umbrella-shaped inflorescences with white or pink flowers, capable of reaching heights of up to 2 meters. It is ideal for wild gardens, woodland edges, or naturalized areas where its impressive size and flowering can add a rustic and wild touch.
Native range
Europe and Western Asia
Care tips
It thrives in full sun to partial shade and prefers moist, well-drained soils rich in organic matter. Although drought-tolerant once established, it appreciates regular watering during dry spells, especially in its first year. A common mistake is confusing it with more invasive and phototoxic Heracleum species; ensure correct plant identification before handling it without protection. It readily self-seeds, so controlling its spread is important if unwanted proliferation is a concern.
