The Plants We Show
The plants illustrated below, and within the picture galleries, represent only a small selection of the known varieties and of those available in cultivation.
Primula a genus of the Primulacae family has more than 400 different species, not counting the thousands of hybrids and cultivars. The genus has been divided into 30 sections, by grouping plants with similarities of leaf, flower form or general habitat.
Found mainly throughout the temperate regions of the northern hemisphere, however a small number of species extend into the tropics and South America.
As a result of their diverse locations, their growing habitats vary between cold alpine conditions and moist woodlands.
With the huge number of species and hybrids it is not possible to go into any great depth, about these beautiful plants, in this website. A number of good publications have been produced on Primulas for those wishing more detailed information.
For showing purposes NAPS Northern separate Primulas into 3 sections, examples above:
‣ Species Primulas - as Primula capitata
‣ Hybrid Primulas - as Primula "Fairy Rose"
‣ Garden Form Vernales Primulas, which include primroses and polyanthus - as Primula "Balarina Valentine"

Auriculas originated from a natural cross between Primula auricula and Primula hirsuta where they grow together in the Alps. The resulting hybrid, Primula pubescens, has been bred for over 400 years to produce the types and quality that we recognise today. Those types and the Standards required are given by the Northern Society as follows:
Show Auriculas have 3 or 4 balanced concentric circles. The inner one is the tube, which should be yellow or golden and like all Florist's (originally meaning a grower of plants, rather than the modern meaning) have no pin (the stigma) visible. Next comes a circle of farina, where tiny hairs are set on the petals so dense that it is like a white paste. The farina is easily marred by rain and even the feet of insects. As such they require protection from the weather especially in the weeks leading up to the shows.
Edged Show Auriculas have the outer half split with the inner part, nearest the paste, being called the body colour. This is of petal consistency and is most often black because this is considered to contrast best with the edge. The fourth circle, called the Edge, is the same consistency as the leaf, an occurrence known as virescence. Florists have used this to produce Edges with a smooth, circular finish where there is no flashing of the body colour. It is farina that differentiates the type of Edge. Where it is absent it is a Green Edge; a thin covering makes it a Grey Edge and a dense covering makes a White Edge.
Edged varieties are considered the most difficult to prepare for the show bench as the pips can take weeks to open and are very variable.
Self Show Auriculas have around half of the pip of one colour. The main colours recognised by classes at the Shows are yellow, red, blue and dark, but there are many shades ranging from cream through to dark brown and purple.
Alpine Auriculas can be distinguished from Show Auriculas by the lack of paste in the eye, indeed they should not have any farina on the plant at all. The tube and eye combine to make a Gold Centre or a Light Centre, the two types of Alpine Auricula. Outside the eye the colourful pips come in shades of red and brown for the Gold Centres and pink through to blue for the Light Centred. These colours in turn shade from dark near the eye to lighter hues at the edge.
Alpine Auriculas are considered easier to grow than Show Auriculas and adapt much better to garden cultivation. However they are probably the most colourful.
Double Auriculas were very popular in the 18th century, but fell out of fashion and were almost lost to cultivation. They have been revived and raised to Florist's standards in recent years in a wide range of colours including striped. The degree of doubling can vary from those with neat camellia like flowers through to full doubles with many petals. The main criteria are that the petals are rounded with no notches and that they fully obscure the central pin.
Striped Auriculas are another recently revived variety and becoming very popular. The stripes should be from the eye to the edge and are usually formed from alternating rays of petal and virescent material. The virescent stripes are often grey or white due to the presence of farina which inhibits their growth. The alternating petal material grows faster and is why the Stripes can show a ragged rather than circular edge. There is a wide range of colours and still plenty of scope for the amateur hybridist.
Fancy Auriculas are the name for those Auriculas that do not fall within any of the above categories. They range form Show Auriculas with red, blue or other body colours that flas to the edge; to shaded Selfs and unshaded and picotee Alpines. Many are chance seedlings but this provides a good seed bed for new classes and types of Auriculas to emerge from.
Border Auriculas are shown for effect rather than to Standards and arealso judged on how they are suited to the garden border. They should be capable of growing into clumps and overwintering without deteriorating in a partially shaded position with moderate water. There is often strong competition in the border classes and some varieties are many years old. They come in a range of mostly pastel colours and should preferably be scented.
