Cotton grass (Eriophorum) isn't actually a grass but rather a sedge that produces distinctive white, cotton-like seedheads measuring 2-3 cm in diameter. This resilient plant thrives in wetland habitats across the Northern Hemisphere, particularly in bogs and tundra regions where it grows 20-70 cm tall. It's remarkably adapted to harsh conditions, featuring specialized aerenchyma tissue that transports oxygen through waterlogged soils and cold-tolerance mechanisms that enable survival at temperatures as low as -40°C. The plant's fluffy seeds can travel several kilometers on the wind, with each seedhead containing 200-400 viable seeds. Its fascinating adaptations and ecological significance hold many more surprises.
INTRODUCTION
Cotton grass (Eriophorum spp.) belongs to the sedge family Cyperaceae and thrives in wetland habitats across the Northern Hemisphere.
Despite its common name suggesting otherwise, this distinctive plant isn't a true grass but rather produces characteristic white, fluffy seedheads that resemble cotton balls dancing in the wind.
The various species, including the widespread E. angustifolium and E. vaginatum, serve as important indicators of healthy bog ecosystems while providing essential resources for wildlife and traditional cultures.
Common Name(s)
Members of the Eriophorum genus are widely known as cotton grass or cottonsedge, though they're not true grasses but rather sedges belonging to the family Cyperaceae. The plant's most recognizable common names derive from its distinctive white, fluffy seed heads that emerge in late summer, resembling tufts of cotton swaying in the breeze.
In different regions, cotton grass has acquired various vernacular names that reflect its appearance and common uses. Native Americans called it "rabbit's tail" or "hare's tail," while in parts of Northern Europe, it's known as "bog cotton" or "moor cotton" due to its prevalence in wetland habitats.
Traditional healers have historically referred to it as "wound grass" for its medicinal properties, particularly its use in treating burns and skin irritations. The Inuit people know it as "pualunnguat" in their language, and they've traditionally used the soft seed heads as lamp wicks and pillow stuffing.
In Scotland, where the plant is particularly abundant, it's sometimes called "canna' downs" or "cotton tops," terms that have become deeply embedded in local folklore and traditional ecological knowledge.
Scientific Name
While common names vary across cultures and regions, the plant's formal scientific classification provides a standardized way to identify it globally. Cotton grass belongs to the genus Eriophorum, which falls within the sedge family Cyperaceae, a diverse group of grass-like plants that thrive in wetland ecosystems.
The taxonomy of Eriophorum includes approximately 25 species, each adapted to specific ecological niches across the Northern Hemisphere. Scientists use binomial nomenclature to distinguish between different cotton grass species, with common examples including Eriophorum angustifolium (common cotton grass), Eriophorum vaginatum (tussock cotton grass), and Eriophorum russeolum (russet cotton grass). Each species name provides insights into the plant's characteristics or habitat preferences.
Cotton grass ecology studies reveal that this genus has evolved specialized adaptations for survival in bog environments. The scientific naming system helps researchers track these adaptations across different species, making it easier to understand their evolutionary relationships and ecological roles.
Modern DNA analysis has confirmed the taxonomic placement of Eriophorum within the Cyperaceae family, though ongoing research continues to refine our understanding of its phylogenetic connections.
Family Classification
Plant taxonomists classify cotton grass within the Cyperaceae family, a vast group encompassing over 5,500 species of sedges worldwide. Within the taxonomy hierarchy, cotton grass shares distinctive characteristics with its sedge relatives, including triangular stems and parallel leaf veins, which help distinguish it from true grasses.
The Cyperaceae family exhibits remarkable genetic diversity, with cotton grass representing just one of its 88 genera. While most family members prefer wetland habitats, cotton grass has adapted specifically to arctic and subarctic environments, demonstrating the family's evolutionary flexibility. This adaptation showcases how members of the same family can develop specialized traits while maintaining core familial characteristics.
Like branches on a family tree, the various cotton grass species form a distinct subfamily within Cyperaceae, known as Cyperoideae. Their unique feature – the elongated, cotton-like bristles that develop after flowering – sets them apart from their sedge cousins.
These distinctive traits have led some botanists to suggest that cotton grass represents one of the more specialized evolutionary branches within the family's diverse portfolio.
QUICK IDENTIFICATION GUIDE
Cotton grass reveals itself through several distinctive characteristics that make field identification straightforward and reliable.
The plant typically reaches heights of 20-70 centimeters with spreading rhizomatous roots that form dense colonies across wet, boggy terrain.
Its most striking feature appears in late spring through summer, when the flowering heads transform into conspicuous white, cotton-like seed tufts that wave gracefully above slender, grass-like stems and narrow leaves.
Height/Spread
Most mature cotton grass specimens reach heights between 30-70 cm (12-28 inches), with individual stalks spreading 15-30 cm (6-12 inches) apart. These growth patterns vary considerably based on habitat preferences, with plants in nutrient-rich wetlands often achieving maximum height potential.
In exposed, windswept locations, specimens tend to remain more compact and develop denser tussocks.
The plant's distinctive white, cotton-like seed heads can extend an additional 5-8 cm above the main stem height, creating an ethereal, floating appearance in the landscape. During peak flowering season, a dense colony of cotton grass might resemble a blanket of snow across the tundra or bog environment.
The underground rhizome system, which enables the plant's spread, typically extends horizontally at depths of 10-15 cm below soil level. This extensive root network allows colonies to gradually expand their territory, with new shoots emerging at regular intervals throughout the growing season.
In ideal conditions, established communities can form extensive patches spanning several meters in diameter, though individual plant spacing remains relatively consistent.
Physical Characteristics
The distinct features of cotton grass make field identification straightforward for both novice and experienced botanists. The plant's most recognizable characteristic is its distinctive white, fluffy seed heads, which resemble cotton balls and can persist for several weeks after flowering.
Cotton grass displays remarkable genetic diversity across its various species, with each variant showing specific ecological adaptations to their environments. The leaves are typically linear and grass-like, measuring 2-5mm in width, with a distinctive bluish-green coloration that helps distinguish them from true grasses.
The stems, which are solid rather than hollow, emerge from dense tussocks and feature specialized cells that enable survival in waterlogged conditions.
Most species produce flowers on multiple stems, each bearing 3-12 pendulous spikelets that transform into the characteristic cotton-like seed heads. These seeds are attached to fine, silky hairs that can extend up to 3cm in length, creating the plant's signature appearance.
The root system is particularly well-adapted to wet conditions, featuring aerenchyma tissue that facilitates oxygen transport through waterlogged soils, an essential adaptation for survival in boggy environments.

While it's most prevalent in northern hemispheric wetlands, distinct species have adapted to various wetland types, creating unique distribution patterns.
The plant often shares its habitat with other moisture-loving species like sphagnum moss and sedges, forming intricate plant communities.
Its distribution significantly follows the patterns of glacial retreat, making it an important indicator species for studying historical climate changes and current ecological shifts in northern ecosystems.
Growing Season
Throughout the year, cotton grass exhibits a well-defined growing season that aligns with the harsh realities of Arctic and subarctic climates. The plant thrives when ideal temperatures hover between 10-15°C (50-59°F), though it can tolerate brief periods of extreme cold.
Growth patterns emerge as snow melts in late spring, with moisture requirements peaking during the essential early development phase. The plant's seasonal variations follow a predictable rhythm: germination begins in May, followed by robust vegetative growth through June and July. Nutrient needs remain relatively modest, as cotton grass has adapted to extract sustenance from nutrient-poor soils that characterize its native habitat.
Soil preferences lean toward acidic, waterlogged conditions with pH levels between 4.0 and 5.5, where pest management rarely poses significant challenges. While companion planting isn't vital for this resilient species, it often grows alongside other bog-dwelling plants that share similar propagation methods.
The distinctive cotton-like seed heads, which inspire the plant's common name, typically reach harvest timing by late August or early September, dancing like delicate lanterns in the autumn breeze.
Growing Conditions
In the heart of wetland environments, cotton grass flourishes across vast stretches of tundra, bogs, and marshlands in the Northern Hemisphere. These resilient plants thrive in areas where soil moisture remains consistently high, often in waterlogged conditions that would prove fatal to many other species.
The plants have adapted to maintain ideal growth in soil pH levels ranging from highly acidic (4.5) to mildly acidic (6.5).
Cotton grass displays remarkable temperature preferences, demonstrating peak performance in cool climates where summer temperatures hover between 10°C and 20°C (50-68°F). Like sentinel guards of the arctic landscape, these hardy plants can withstand extreme cold, with some species surviving temperatures as low as -35°C (-31°F) during winter dormancy.
The plants require full sun exposure and show reduced vigor in shaded conditions, though they'll tolerate partial shade in warmer regions. Their extensive root systems, which can penetrate up to 30 centimeters deep, allow them to anchor firmly in saturated soils while accessing nutrients that might be scarce in their nutrient-poor habitats.
ARCTIC ADAPTATIONS
Cotton grass displays remarkable cold tolerance mechanisms through its specialized cellular adaptations, which prevent ice crystal formation in its tissues even at temperatures well below freezing.
The plant's circadian rhythms have evolved to function during the extreme light conditions of the Arctic, allowing it to photosynthesize effectively during 24-hour daylight in summer while conserving energy during the dark winter months.
Its extensive root system penetrates deep into the permafrost's active layer, anchoring the plant securely while accessing pockets of liquid water and nutrients that remain available even when surface soils are completely frozen.
Cold Tolerance Mechanisms
Harsh winters and freezing temperatures pose little threat to cotton grass thanks to several remarkable adaptations. The plant's frost resistance mechanisms allow it to survive in temperatures as low as -40°C, maintaining cellular integrity through specialized proteins and sugars that act as natural antifreeze compounds.
Cotton grass's temperature adaptation involves complex biochemical changes that occur as temperatures drop. Its cells actively accumulate soluble sugars and modify membrane lipids, creating remarkable flexibility in freezing conditions.
Like a well-insulated house, the plant's tissues maintain critical functions even when surrounded by ice. The species has developed specialized vascular tissues that prevent the formation of damaging ice crystals within its cells.
During winter dormancy, cotton grass reduces its water content and redistributes essential nutrients to underground storage organs, much like a bear preparing for hibernation. These underground rhizomes remain protected beneath the soil's insulating layer, while surface tissues enter a state of suspended animation until spring arrives.
This sophisticated cold tolerance system enables cotton grass to thrive in Arctic and subarctic regions where many other plants can't survive.
Light Response (24-hour cycles)
Remarkable photoperiod adaptations allow cotton grass to flourish under the Arctic's extreme light conditions, where summer brings constant daylight and winter plunges into extended darkness. The plant's highly specialized photosynthesis efficiency enables it to maximize energy production during the brief growing season, converting nearly 90% of available light into usable energy.
Cotton grass maintains its circadian rhythm despite the unusual light patterns through a sophisticated internal timing mechanism. This biological clock continues to regulate essential functions like stomatal opening and chlorophyll production even when external light cues are constant or absent.
During the midnight sun period, the plant modulates its photosynthetic rate to prevent overexertion, effectively creating artificial "night" periods through biochemical responses.
The species has evolved to recognize subtle changes in light quality rather than relying solely on day length. By detecting variations in the blue-to-red light ratio and light intensity, cotton grass can anticipate seasonal changes.
This remarkable adaptation allows it to prepare for dormancy well before the polar night begins, storing resources and adjusting its metabolism to survive months of darkness.
Permafrost Survival Strategies
Beyond its mastery of extreme light conditions, cotton grass has developed sophisticated root systems and metabolic processes to thrive in permafrost environments. Its remarkable permafrost resilience stems from specialized roots that can penetrate frozen soil layers up to 30 centimeters deep, accessing nutrients that remain locked away from other plants.
The plant's climate adaptation features include an extensive network of fine root hairs that can rapidly absorb water during the brief summer thaw. These roots function like miniature heating elements, generating enough warmth through metabolic activity to create micro-thaw zones in the surrounding permafrost.
Cotton grass also produces antifreeze proteins that protect its cellular structures from ice crystal damage during deep freezes.
Perhaps most impressive is the species' ability to maintain photosynthetic activity at temperatures as low as -5°C, while storing essential nutrients in specialized rhizomes that act as underground survival bunkers.
This adaptive strategy allows cotton grass to resume growth immediately when conditions improve, making it one of the Arctic's most successful pioneer species in areas where permafrost is beginning to thaw.
REPRODUCTION
Cotton grass launches its reproductive cycle in late spring, when delicate white flowers emerge from the tips of sturdy stalks across the tundra landscape.
Wind serves as the primary pollination vector, carrying pollen between plants and facilitating cross-fertilization in these resilient Arctic perennials.
Following successful pollination, the seeds develop with distinctive white, cotton-like bristles that aid in wind dispersal, allowing them to drift considerable distances across the Arctic terrain before settling to begin their growth cycle anew.
Flowering Period
During late spring and into early summer, cotton grass produces its distinctive white flowering heads that resemble tufts of cotton. These flowering characteristics vary depending on the species, with some varieties blooming as early as May while others don't flower until mid-June.
The flowering period typically lasts between four to six weeks, during which the plant's small, inconspicuous brown flowers develop into the iconic cotton-like seed heads. Environmental conditions and geographical location greatly influence the timing, with plants in northern latitudes flowering later than their southern counterparts.
In regions experiencing seasonal variations, cotton grass might display staggered flowering periods across different populations. As temperatures rise and daylight hours increase, the plant's flowering response intensifies, leading to synchronized blooming across vast peatland areas.
The flowering stems can reach heights of 30-70 centimeters, making the white seed heads highly visible across their habitat. This timing coincides perfectly with ideal wind conditions for seed dispersal, as spring and early summer breezes help distribute the fluffy seeds across considerable distances.
Pollination Method
Wind serves as the primary pollination method for cotton grass, carrying pollen between plants across expansive peatland environments. The plant's unique pollination strategies have evolved to maximize reproductive success in harsh northern habitats, where insect pollinators are often scarce. Small, lightweight pollen grains are released from the plant's anthers during favorable conditions, allowing them to travel considerable distances on air currents.
These reproductive adaptations reflect millions of years of evolution in open, windswept environments. The flowers' elevated position on tall stems, typically reaching 30-60 centimeters in height, facilitates effective wind pollination by positioning the reproductive structures above surrounding vegetation.
Cotton grass's flowering heads are designed to swing freely in the breeze, which helps disperse pollen grains more efficiently. The stigmas of female flowers are specially adapted with feathery surfaces that effectively catch airborne pollen, increasing the chances of successful fertilization.
This wind-dependent system proves remarkably efficient, with a single plant capable of releasing thousands of pollen grains, ensuring the species' continued survival in challenging arctic and subarctic ecosystems.
Seed Dispersal
After pollination, the distinctive white, fluffy seed heads of cotton grass emerge as its primary dispersal mechanism. These seed heads contain numerous tiny fruits, each attached to long, silky hairs that can extend up to 3-5 centimeters in length.
The elongated hairs serve as nature's parachutes, enabling efficient wind dispersal across vast distances when conditions are favorable. During late summer and early autumn, these cotton-like tufts catch even the slightest breeze, carrying seeds up to several kilometers from their parent plants.
The lightweight design of these aerial transporters guarantees maximum distribution potential while maintaining seed viability throughout the journey.
Cotton grass's dispersal strategy proves particularly effective in open tundra and moorland environments, where unobstructed wind patterns facilitate widespread seed distribution. The timing of seed release coincides with seasonal wind patterns, which helps establish new colonies in suitable wetland habitats.
Studies have shown that individual seed heads can contain between 200-400 seeds, and under ideal conditions, successful germination rates can reach 60-70 percent when seeds land in appropriate moist environments.
Lifecycle Stages
Throughout spring and early summer, cotton grass initiates its reproductive cycle with the emergence of flower heads containing both male and female reproductive structures. During this significant phase, the plant develops small, inconspicuous flowers that cluster together on spikes, typically measuring 2-4 centimeters in length.
The lifecycle stages progress through distinct growth phases, beginning with pollination by wind in late spring. Once fertilization occurs, the characteristic white, fluffy seed heads develop, expanding to lengths of 3-5 centimeters. These cotton-like bristles serve as nature's parachutes, enabling effective seed dispersal.
The plant's maturation continues as seeds develop within protective bracts, taking approximately 4-6 weeks to reach full ripeness. During autumn, the parent plant enters dormancy while released seeds settle into new locations, where they'll remain dormant through winter.
The following spring, when soil temperatures reach 10-15°C, germination begins, and young seedlings emerge to restart the cycle. These tiny pioneers establish themselves in wet, acidic conditions, developing robust root systems that anchor them in their boggy habitat.
