Overview

Carex vulpina is a robust, densely tufted perennial sedge in the Cyperaceae family, growing 18–36 inches (45–90 cm) tall in dense tussocks 12–18 inches (30–45 cm) across. Stems are triangular, sharply angled, with distinctly winged angles that cut the skin when drawn through the fingers — a key tactile identification character. Leaves are flat, 0.2–0.4 inch (5–10 mm) wide, bright green to yellow-green, rough-margined. The inflorescence is a dense, compound spike 1.5–3 inches (4–8 cm) long, composed of numerous tightly packed, ovoid spikelets forming a continuous or slightly interrupted column. The inflorescence is fox-tail-like in shape — the basis for the common name and the epithet vulpina (fox-like). Spikelets are brownish-green, each containing both male and female flowers. Utricles are 4–5 mm long, broadly ovoid, flattened, with a winged margin and a bifid beak, spreading at maturity to give the spike a bristly texture. The species occurs in wet meadows, ditch margins, and floodplain habitats on nutrient-rich, base-rich, alluvial soils across Europe. In Britain, it is a species of conservation concern, declining due to drainage and agricultural improvement of its floodplain grassland habitat. Not to be confused with C. otrubae (false fox sedge), which is much more common and frequently misidentified as C. vulpina.

Native Range

Carex vulpina is native across Europe, from the British Isles and Scandinavia south to the Mediterranean and east through Russia to western Siberia. It occurs in wet meadows, floodplain grasslands, ditch margins, and pond edges on base-rich, nutrient-rich, alluvial soils from sea level to approximately 3,300 feet (1,000 m).

Suggested Uses

Used in wet meadow restoration, floodplain grassland recreation, and pond margin plantings on base-rich soils. In Britain and Europe, a conservation-priority species for wet meadow habitat restoration. In garden settings, plant at pond margins and in rain gardens where nutrient-rich, base-rich wet conditions can be maintained. The dense tussock habit and fox-tail spikes add textural interest to naturalistic wet plantings.

How to Identify

Identified by the robust tussock habit, sharply winged triangular stems that cut when pulled through the fingers, and the dense, fox-tail-shaped compound spike of brown-green spikelets. Distinguished from C. otrubae (false fox sedge) — the most commonly confused species — by the winged stem angles (C. otrubae stems are not winged), the broader utricles, and the preference for base-rich floodplain soils. The stem-wing character is the most reliable field distinction between the two species.

Flowering from May through June. The dense compound spike sheds pollen by wind over a 2–3 week period. Utricles ripen and spread to a bristly texture by July–August. Seed dispersal is by water (hydrochory) during floodplain inundation events.

Care & Maintenance

Care Guide

Plant in full sun to partial shade in consistently moist to wet, base-rich, fertile soil with a pH of 6.5–8.0. Space 12–15 inches (30–38 cm) apart. Tolerates seasonal flooding and standing water to 3 inches (8 cm). In garden settings, plant in rain garden lower zones, pond margins, and wet meadow areas. Feed is unnecessary on fertile alluvial soils. Do not allow to dry out — the species is restricted to permanently moist habitats.

Pruning

Cut back dead foliage and old spikes to 3–4 inches (8–10 cm) in late winter before new growth. No other management required.
