The spring of 2026 has been an exceptional one for primroses Primula vulgaris in Assynt, and on 9th May, before they went over, I was moved to photograph them at a couple of local sites.
Gleann Ardbhair
South-facing slopes of the steep-sided embankment of the B869 on the eastern side of this glen (NC1833) bore sheets of flowers (photos 1-4).
Smaller plants were thinly scattered through adjacent woodland, and also along the banks of the Allt Ardbhair below the bridge in the bottom of the glen (photo 5).
However, the sheer abundance of those higher up the hill is almost certainly an unintended consequence of the construction of this road in the first decade of the 20th century. It provided an expanse of steep, open, sunlit, fertile ground irrigated by run-off from the road surface, which has persisted for well over a century.
There were a couple of small bonuses. Two recently-emerged speckled wood butterflies were spiralling around one another in open woodland high on the hill.
I also spotted, in a wet area of the embankment just to the east of the bridge, the pale-backed leaves of melancholy thistle Cirsium heterophyllum (photo 6), whose large solitary magenta heads will be a fine sight later in the year.
Oldany
On crags above the east bank of the Oldany River, between the northern two of the three bridges which cross it not far above its estuary (NC1032), there are patches of native woodland (photo 7).
Driving along the road recently, I noticed a dense scatter of primroses below one patch, and on 9th May I took a closer look. They were indeed abundant on a steep grassy bank that gets plenty of sunshine (photos 8-9).
Bonuses on this site were two more spring-flying butterflies, a worn over-wintered peacock (photo 10) and a freshly-emerged spring-brood male green-veined white (photo 11).
Discussion
In the Flora of Assynt (2002) we described primroses as ‘common and widespread where there is some shade or shelter’. They are indeed widespread, mapped for 135 of the164 tetrads (2km squares) which were our survey units, and absent only from some montane ones (photo 12).
However, common was, on reflection, an over-simplification, since they are distinctly patchy in their occurrence. Driving from Lochinver to Unapool along the coast road one cannot fail to notice this when they are in flower. Primroses are conspicuous to the north of Achmelvich Bridge (NC0824) and west of Rhicarn (NC0725) and then become very scarce until Oldany (NC0932), where roadworks have spread them from the steep wooded western bank of Fank Brae onto the verge opposite, as also a little further north in the woodlands mentioned above. They crop up in wooded areas around Nedd and Glenleraig (NC1332 and 1431), but only become noteworthy again towards Gleann Ardbhair.
They are not so obvious elsewhere in the parish. On a drive to Ullapool on 11th May, we noted a few at Little Assynt ((NC1625), and more on the limestone east of Skiag Bridge (NC2324), and at Knockan (NC2110 and 2010). However, they do turn up in penny numbers all over the parish, especially on the banks of watercourses, where later in the year we find their leafy rosettes.
I have been trying to make sense of the local distribution, especially where they are present in quantity. Much further south, in landscapes now dominated by intensive agriculture and forestry, the primrose is regarded as an ‘ancient woodland indicator’, together with other iconic species such as bluebell Hyacinthoidesnon non-scriptus and wood anemone Anemone nemorosa.
However, in the wetter, milder and, thankfully, wilder landscapes of North-West Scotland this is not a useful description of its preferred habitats, which I would describe as on well-drained but nevertheless moist, nutrient-rich soils, often in shade, not necessarily that of trees.
There may well be an association, especially along the north coast of Assynt, with the mineral-rich soils derived from glacial deposits that occur on the steeper sides of many glens. But that is, after all, where most of our native woodland has survived.
It would be really interesting to plot their precise distribution throughout one of the better-wooded coastal townships in Assynt to see what that revealed. Meanwhile we can enjoy quite the best showing of primroses in several decades, which is probably weather-related.
