Primrose, cowslip, oxlip – these names all refer to members of the genus Primula. This large genus, comprising about 500 species, is native to temperate areas of the Northern Hemisphere and southern South America, and also to tropical mountains in Ethiopia, Indonesia and New Guinea. A core area is Central Asia, China, and the Himalaya, which is home to almost half of the species.

 

Cow dung’
The generic name is a diminutive of the Latin prima (’first’), referring to the early flowering of several species. Many of these plants are indeed very hardy, as seen on the pictures above.

The name primrose is from the Latin prima rosa, meaning ‘the first rose’, although primroses are not at all related to roses.

According to some authorities, the name cowslip is a corruption of an Old English word, cuslyppe, meaning ‘cow dung’. This probably refers to the favoured habitat of the common cowslip (Primula veris), namely dry slopes, grazed by cattle. Others claim that the word is a corruption of cow’s leek, derived from the Anglo-Saxon word leac, meaning ‘plant’.

It has been said that the name oxlip, which is a corruption of ox and slip, refers to the fact that oxlip, like cowslip, often grows on cattle grazing grounds. This may be a wrong presumption, as true oxlip (Primula elatior) – at least in the northern part of its distribution area – mainly grows in forests.

 

European primroses
The Alps alone are home to 25 species of primrose. A selection of these may be studied on the page Plants: Flora of the Alps and the Pyrenees.

 

Primula elatior True oxlip
True oxlip is found throughout Europe, northwards to Denmark and southern Sweden, and in northern Asia, eastwards to the Altai Mountains. It mainly grows in hardwood forests, where it blooms before foliation of the trees. In the Alps, subspecies intricata is found in open, grassy areas at high altitudes.

Primula farinosa Birdseye primrose
This fine little plant has a very wide distribution, from northern Europe across northern Asia, with isolated populations in the mountains of southern Europe. The specific name is derived from the Latin farina (‘flour’), alluding to the fine grains on the stem.

 

 

Birdseye primrose often forms large populations, as in this picture from a littoral meadow on the island of Bornholm, Denmark. The blue flowers are common butterwort (Pinguicula vulgaris). (Photo copyright © by Kaj Halberg)

Primula glutinosa Sticky primrose
This plant has stiff, upright, serrated, glutinous, and fleshy leaves. Its flowers are bluish-violet, the sepals covered by dark bracts. It is found in the central and eastern Alps, where it often grows at high altitudes, up to 3,250 m. The specific name is from the Latin gluten (‘glue’), alluding to the sticky glands on the leaves.

Primula minima Least primrose
This species is easily identified by the rather large, deeply cut petals and the diminutive leaves. It is quite common in the eastern half of the Alps, growing at altitudes between 2,000 and 3,000 m.

Primula veris Common cowslip
A very common species in large parts of Europe and western Asia. The specific name is the genitive case of ver (’spring’), referring to the flowering time of this species.

Popular names include key flower, Herb Peter, and Our Lady’s keys, the first two referring to the inflorescence, which resembles a bunch of keys, the emblem of St. Peter. According to legend, St. Peter heard that some people were trying to enter heaven by the back door, instead of the front gates, which were guarded by him. Hurrying towards the back door, he dropped his keys, which took root and became cowslips. German names of this species include Echte Schlüsselblume, meaning ‘true key flower’, and Himmelsschlüssel, meaning ‘keys of heaven’.

In Norse mythology, the flower was dedicated to Freya, called the Key Virgin, a goddess associated with love, beauty, and fertility. When the heathens converted to Christianity, the plant was instead dedicated to Virgin Mary, hence the name Our Lady’s keys.

Common cowslip has been utilized medicinally for hundreds of years. This usage is described on the page Plants: Plants in folklore and poetry.

In A Midsummer Night’s Dream, by William Shakespeare (1564-1616), a mischievous puck, or spirit, Robin Goodfellow, meets a fairy, asking her what she is doing. She says:

 

And I serve the fairy queen
To dew her orbs upon the green,
The cowslips tall her pensioners be,
In their gold coats spots you see,
Those be rubies, fairy favours,
In those freckles live their saviours,
I must go seek some dewdrops here,
And hang a pearl in every cowslip’s ear.

 

Modified into today’s English:

 

I serve the fairy queen,
Adding dew drops to her flowers in the grass.
The tall cowslips are her servants.
In their golden coats you can see spots.
Those are rubies, gifts from the fairies.
Their sweet smell comes from those freckles.
Now I must go to find some dewdrops,
And hang a pearl earring on every cowslip flower.

Primula vulgaris English primrose
This species, also called P. acaulis, is among the earliest flowering plants of northern Europe, in mild springs blooming as early as the beginning of March. Three subspecies of this plant are recognized, native to Europe, north-western Africa, and south-western Asia, eastwards to Iran. The nominate vulgaris, which is distributed in northern, western, and southern Europe, has pale yellow flowers, whereas balearica, which is endemic to the Balearic Islands, has white flowers. The third subspecies, sibthorpii, is found in the Balkans and south-western Asia. It has pink, red, or purple flowers.

Himalayan primroses
Primroses probably originated in the Himalaya, where a bewildering array of species is found, about 72 in total. They vary greatly in size, ranging from 5 cm high dwarves to robust plants almost 1 m tall. A number of Himalayan species are presented below. They are described in depth on the page Plants: Flora of the Himalaya.

 

Primula atrodentata
This tiny plant grows in open areas at altitudes between 3,500 and 4,900 m, distributed from Uttarakhand, north-western India, eastwards to south-eastern Tibet.

Primula denticulata
The most abundant primrose in the Himalaya, growing in forest clearings and grassy areas. It has a broad altitudinal range, found at elevations between 1,500 and 4,500 m, from Afghanistan eastwards to Myanmar. As a rule, the inflorescences of this very variable species become larger and denser with higher altitude.

Primula strumosa Golden-eyed primrose
Usually, this species has bright yellow flowers, but it hybridizes freely with the purple P. calderiana, sometimes resulting in yellow, white, blue, and purple flowers in a single population. It is found in the eastern Himalaya, from Nepal eastwards to China, at altitudes between 3,500 and 4,300 m.

Primroses with several umbels
The inflorescence of some primrose species differs from those of most other members of the genus in that the flowers are arranged in several umbels up the stem. Two such examples are shown below.

 

Primula floribunda
This species with pretty, golden-yellow flowers grows on humid rocks, from Afghanistan eastwards to western Nepal.

Hybrids
Where cowslip, English primrose, and/or true oxlip grow together, hybridization often takes place between them. In Denmark, a good place to study these hybrids is in the forest at the white cliffs on the island of Møn, where all three species occur.

Primroses as offerings
In the Himalaya, offerings to stone cairns, sacred trees etc. indicate remnants of pre-Hindu and pre-Buddhist animism. In the picture below, Hindu men are placing a flower offering, consisting of yellow Primula stuartii, yellow Geum elatum, and blue and white Anemone obtusiloba, on a stone cairn – a shrine dedicated to a local Hindu goddess atop Rakhundi Peak (3622 m), Great Himalayan National Park, Himachal Pradesh, India. This goddess is probably a form of Devi, the god Shiva’s shakti (female aspect), as the trident is a symbol of Shiva.

Anemone obtusiloba and Geum elatum are described on the page Plants: Flora of the Himalaya, whereas animism is dealt with in detail on the page Religion: Animism.
