Geranium erianthum, commonly known as Woolly Geranium, is a perennial herb that is native to a variety of habitats including moist forests, meadows, and streambanks in subalpine and alpine regions in Canada and Alaska. It is found across a wide geographic range, including parts of China, Japan, Russia, North America, and has been introduced to England. This species typically grows to a height of 12-24 inches (30-60 cm) and spreads 12-18 inches (30-45 cm). Woolly Geranium is characterized by its large palmate leaves covered in soft hairs, giving them a woolly texture, and its showy lavender to purple flowers that bloom in the summer months. The flowers are quite attractive and can add a splash of color to garden settings.

Woolly Geranium is valued for its ease of maintenance and its ability to thrive in a variety of soil conditions, though it prefers moist, well-drained soils. It is often used in borders, woodland gardens, and as ground cover due to its attractive foliage and flowers. It requires partial to full sun exposure and regular watering, especially in drier climates. While generally disease-resistant, it can occasionally suffer from rust or leaf spot. Woolly Geranium is not known for aggressive roots or significant invasiveness, making it a safe choice for most gardens. It is also appreciated for its tolerance to cold temperatures and can be a good choice for higher elevation gardens.CC BY-SA 4.0
