Primula 'vialii' (Vial's Primrose)

Where to Plant:

Often known as the Orchid Primrose, this is a truly unique and beautiful plant with a striking flower spike of crimson buds opening from the bottom up into a cone of lilac-purple flowers. Unlike many primroses, it thrives in a position in partial shade in a moisture-retentive, humus-rich soil. It is an excellent choice for a damp border, a bog garden, or alongside a pond where its roots will not dry out during the summer months. It dislikes hot, direct sun.

How to Plant:

Plant container-grown specimens in spring or summer. Dig a hole and enrich the soil with plenty of well-rotted organic matter such as leaf mould or garden compost, which will help to retain the moisture this plant loves. Gently place the plant in the hole, ensuring the crown is level with the surrounding soil. Backfill, firm gently, and water in well. They are most effective when planted in small groups or drifts.

Aftercare:

The most important part of its care is to never allow the soil to dry out completely, particularly during hot summer spells. Applying a mulch of bark or compost can help to conserve moisture. Primula vialii is often a short-lived perennial, so to ensure its continued presence in your garden, it is a good idea to allow it to self-seed, or to collect and sow the seed yourself. Dividing established clumps every couple of years can also help to maintain vigour.
