Heracleum sphondylium subsp. sibiricum, commonly known as Siberian Cow Parsnip or Eltrot, is a perennial herb native to temperate Eurasia, including meadows, forest clearings, riverside scrub, and semi-natural habitats. It is often found in areas with a history of human disturbance such as road verges and waste places. This species grows at a moderate rate to a typical height of 3-5 feet (0.9-1.5 meters) and a width of 1-2 feet (0.3-0.6 meters). The plant features large, compound leaves and stout, hollow stems. Its inflorescence is a compound umbel of white flowers, which are showy and bloom in the summer, attracting a variety of pollinators.

Siberian Cow Parsnip is valued for its architectural presence in the garden, with its large leaves and tall flower stalks providing a dramatic visual impact. It is suitable for naturalistic plantings, wildlife gardens, and as a background plant in borders due to its height. It thrives in full sun to part shade and prefers medium draining loam or clay soils, with medium water requirements. While it can be a striking addition to the garden, it is important to note that Heracleum sphondylium subsp. sibiricum can be invasive outside its native range and may cause skin irritation upon contact. Gardeners should exercise caution and check local regulations before planting.CC BY-SA 4.0
