Soft-Rush Pith: The Forgotten Firestarter That Lit Winter Nights
From a distance, with a touch of imagination, they resemble a prickle of porcupines scattered across the landscape. Upon closer inspection, these are spiky clumps of soft-rush, scientifically known as Juncus effusus. This native plant thrives in our evolving climate, particularly after mild, wet winters that tip the balance in its favour for dominating waterlogged grazing lands. With its prolific seed-setting and relentlessly spreading rhizomes, it creeps further across pastures each year, often overlooked as one of the least charismatic members of our native flora.
The Hidden Beauty Within
Superficially, soft-rush appears unassuming, with bundles of long, olive green, quill-like leaves. However, splitting these open reveals a hidden beauty: inside lies a spongy pith packed with tiny silver star-shaped cells. In botanical terms, this is called stellate parenchyma, where the rays of these cells join at their tips to form a intricate three-dimensional lattice. This structure is not just aesthetically fascinating but historically significant.
A Glimmer in the Darkness
Two centuries ago, before electric light became accessible at the flick of a switch, soft-rush pith provided a glimmer of light during the long hours of winter darkness. Illumination after dusk typically came from fires in grates, oil lamps, or candles for those who could afford them. From 1709 until 1830, successive governments imposed an ever-increasing tax on candles, which could only be legally purchased from authorised dealers. This financial burden forced the rural poor to seek alternative sources of light, leading them to rushlights.
The Making of Rushlights
Soft-rush pith, being spongy and absorbent, was encased in layers of animal fat to create wicks for rushlights. These makeshift lights sputtered for about 20 minutes, emitting a smoky, smelly flame that produced roughly the same amount of light as a modern-day safety match. Interestingly, the light output could be doubled by "burning the candle at both ends," a phrase that has since entered common parlance. Making rushlights was often a task assigned to "decayed labourers, women, and children," as noted by the naturalist Gilbert White in The Natural History of Selborne (1789). He calculated that 1,600 stripped rush piths could provide wicks to light 800 hours of winter darkness, highlighting their efficiency and necessity.
A Personal Attempt and Historical Context
Inspired by historical accounts, one might try to prepare rushlights following instructions from William Cobbett, a champion of the rural poor and campaigner for the abolition of the candle tax. In his 1823 publication, Cottage Economy, Cobbett, who was "bred and brought up mostly by rush-light," detailed the process: "Take off all the green skin, except of about a fifth part of the way around … necessary to hold the pith together." However, this task often proves challenging, requiring nimbler fingers and sharper nails than many possess today, leading to abject failure for modern attempts.
This exploration into soft-rush pith not only sheds light on a forgotten aspect of rural history but also underscores the resilience and ingenuity of past communities in the face of adversity. As we look again at these unassuming spiky bundles, we recognise them as more than just plants—they were vital firestarters that brought a little light to the dark winter nights of yesteryear.
