Heracleum sphondylium subsp. pyrenaicum, commonly known as Pyrenean Hogweed, is a perennial herb native to a variety of habitats in Western Europe, mainly found in the Balkans and mountain ranges of Europe. It typically grows at a moderate rate to a height of 5-8 feet (1.5-2.4 meters) and a width of 2-3 feet (0.6-0.9 meters). This subspecies features large, compound leaves and a stout, hollow stem. The white flowers are arranged in large, umbrella-like clusters known as umbels, which are quite showy and bloom in the summer. The plant is also noted for its large, lobed leaves and bristly stems.

Pyrenean Hogweed is valued for its architectural presence in the garden, with its tall stature and large inflorescences making it a striking feature when in bloom. It is used for naturalistic plantings and as a specimen in large borders or wildflower gardens. It prefers full sun to part shade and thrives in medium draining clay or loam soils. Regular watering is necessary to keep the plant healthy, especially in drier climates. While it can be a beautiful addition to the garden, Heracleum sphondylium subsp. pyrenaicum is potentially invasive outside its native range, and gardeners should be cautious about planting it in areas where it may spread uncontrollably.CC BY-SA 4.0
