Allion's Primrose

A true gem of the alpine world, Primula allionii is native to a very small area of the Maritime Alps. It forms a tight cushion of grey-green, sticky leaves. In early spring, it produces an abundance of flowers that range from pale pink to deep rose-purple, often with a white eye. The flowers are usually so numerous that they completely hide the foliage. In the UK, it is primarily grown as an alpine house plant because its hairy, sticky leaves are very susceptible to rot if they get wet in winter. However, it can be grown outdoors in a perfectly drained, north-facing crevice or under a projecting rock to keep off the rain. It is a frequent prize-winner at alpine shows. It requires a very gritty compost and must be watered carefully from below. It is a slow-growing, long-lived plant that is highly rewarding for those prepared to meet its exacting needs for ventilation and drainage. It represents the height of alpine plant beauty and specialist cultivation.
