Primula allionii are easier to grow in pots than open ground but they repay a bit of effort. In an alpine house they can live for over 25 years providing many blooms in that time.

Primula allionii have been cultivated for over 100 years and there are many forms some being more vigorous than others.
They are endemic to the French and Italian maritime Alps.
I have just bought a plant from the local AGS society Primuls allionii Anna Griffith.

Primula allionii cross with at least 7 other primula species including auricula which produced the Lismore Yellow above. Most of these hybrids are compact plants but vary in size of flower.

Primula allionii Cultivation Tips
Pot in John Innes no2 with 25% added grit or sand.
Top dress with a layer of chippings or fine grit.
Water from below to keep leaves and stems as dry as possible.
Light shade is best in summer from April- September.
Damaged leaves and dead flowers can be removed with a slight sideways pull.
Pot on young plants each year and older plants when the roots reach the pot side.
Cuttings taken in summer will root in damp sand or mixed with peat.

Growing Primula allionii Outdoors
Plants must be protected from the wet.
A crevice garden or overhang may be suitable, as is some tufa protection (shown above).
A northerly aspect helps prevents excessive drying out.
If necessary try winter protection from a sheet of glass.
