In my watercolour botanical illustration of the harestail cotton grass, Eriophorum vaginatum, I aimed to capture the delicate beauty and ethereal quality of its slender stems and wispy white tufts. This piece highlights the intricate details and subtle textures that make this plant so captivating, as observed during my hikes on the Bennachie and the local hills. This painting was one of my final five pieces for the Royal Botanical Garden’s Diploma course.

Ecological Significance of Harestail Cotton Grass
Harestail cotton grass plays a crucial role in its ecosystem, helping to stabilise soil in wetland areas and regulate water levels within peatlands, which are critical carbon stores. Despite its delicate appearance, this plant thrives in harsh environments thanks to a robust root system that anchors it in low-nutrient, saturated soils with limited light.
Unique among its species, Eriophorum vaginatum produces single spikelets that form its characteristic tufts, distinguishing it from other varieties like Eriophorum angustifolium, which is known for its multiple flower heads. These differences highlight the incredible diversity within the cottongrass family, each adapted to its specific habitat within Scotland’s bogs and wetlands.
Cultural and Historical Value of Harestail Cotton Grass
As I painted, I reflected on the historical and cultural significance of harestail cotton grass in Scotland. Once commonly used in thatching for its natural insulation and resilience, it was also valued in traditional Scottish medicine, where extracts were used to soothe and heal minor wounds.
Conservation efforts today underscore the importance of Eriophorum vaginatum in supporting local wildlife, providing nesting material for birds, and shelter for insects that play essential roles in the ecosystem.
