Stunning and unique!! However, slugs absolutely adore them, which can be tricky when the young plants are still small. But once they're well established (and watered regularly), they flowered generously and for quite a long time—from mid-May until the end of June (more timidly in July). I need to get more of them; I want loads around my pond because they're so beautiful (very vibrant color, just like in the photos). This primrose isn't very well-known, but it's definitely worth it.

Description

The Primula vialii, known as Vial's primrose or the orchid primrose, resembles a terrestrial orchid more than a classic primrose. Its erect, conical spikes bear carmine-red buds that open from the bottom upwards into small lilac-mauve flowers, forming a mauve base topped with a red tip. This unusual Chinese species does not go unnoticed in damp, partially shaded areas of the garden.

This plant belongs to the Primulaceae family, like all primroses. It is a herbaceous perennial: its leaves and stems die back during the cold season, and the stump then forms a new rosette in spring. It grows naturally in damp meadows, near watercourses, and among the scrub of mountain valleys in Sichuan and Yunnan, at altitudes between 2,800 and 4,000 m. Described by botanists at the end of the 19th century, it was also known as Primula littoniana, now considered a synonym. Its current name pays tribute to the missionary Paul Vial. The species has received the Royal Horticultural Society's Award of Garden Merit. The plant forms a rosette 20 to 30 cm wide. Its lanceolate leaves, light to medium green, can reach 15 to 30 cm in length. They are slightly hairy with edges that are gently curled under. The flower stems, firm and erect, rise to 40 or 50 cm. Each flower spike gathers a great many small tubular flowers. The calyces and buds are a deep carmine red; the corollas turn mauve-pink to lilac-violet as they open. Flowering occurs in June and July. This primrose's hardiness reaches at least –15 °C in well-drained soil.

A demanding perennial, Primula vialii enjoys partially shaded positions, acidic, moist, light, and very humus-rich soils, without excess water in winter. Grow it on the banks of a pond, in a cool, shaded rockery, or at the edge of woodland in the company of shooting stars, Podophyllum, dwarf Astilbes and other ligularias. As its lifespan is relatively short (a few years), it is best to divide it every year, or let it self-seed in a favourable spot.

Planting and care

Primula vialii can be planted from February to April or from September to November, outside periods of frost or intense heat. Partial shade provides it with a cooler atmosphere; full sun is possible in oceanic or montane climates if the soil never dries out in summer. The soil should be deep, loose, rich in humus, acidic to neutral, and free of active lime. Clay soil can accommodate it if it is aerated and does not retain water during winter. In compact ground, adding leaf mould and mature compost, paired with slightly raised planting, improves conditions around the stump. Regular watering is necessary during the first summer and during dry spells, even for a well-established plant. An organic mulch keeps the roots cool. The young leaves should be monitored in spring, as they attract slugs. A sufficiently strong clump can be divided in early spring.
