Disappointed by this flower, which is pretty but whose heart turns brown as if the plant lacked rain.

Description
The Lychnis flos-cuculi 'Petit Henri' is a very pretty variety of Ragged Robin with very double, tousled, pure white flowers. This adorable little perennial plant, also known as Ragged Robin, is sturdy despite the delicate appearance of its flowers. Its small, ethereal flowers, very abundant, appear throughout the summer, carried by surprising purple stems. It is a fully hardy plant that thrives in moist soils and the edges of sunny ponds. Its light flowering, animated by the slightest breeze, softens the stiffness of other perennials, and it works wonders in natural gardens.
This Ragged Robin belongs to the Caryophyllaceae family; it is a cousin of carnations. It is named like this because it blooms when the cuckoo sings. It is an upright perennial that thrives in wet areas of Europe (marshes, bogs) and can also be found in meadows up to 2500 m (8202ft) altitude. The variety 'Petit Henri' is a newcomer, a cousin of the very popular 'Petite Jenny' with which it shares all its qualities.
Its base is a stoloniferous stump producing a low, compact clump composed of bright green lanceolate spatulate leaves, semi-evergreen, which can reach 12 cm (5in) long. From this base emerge in May-June branched, slightly leafy, reddish-purple stems, about 40-60 cm (16-24in) tall, which bear at their tips bell-shaped calyx clusters, whitish in color, veined with red. The calyxes open to release pom-pom flowers of immaculate white, about 3 cm (1in) in diameter, composed of multiple deeply cut petals forming fine strips. These flowers have the great advantage of not yellowing with age. The Lychnis flos-cuculi self-seeds spontaneously, not always identical to the mother plant.
Their rather slender habit encourages grouping Lychnis flos-cuculi to create a fluffy mass effect. Excellent cut flowers, they are also perfect for English gardens and the cool, humid English climate. You can plant them near a body of water or in any moist to cool soil, preferably in the sun, with companions that appreciate the same conditions, such as pink astilbes, candelebar primroses, coral-flowering heucheras, or Virginia bluebells and white or pink obedient plants. Their association with peonies and grasses (small Miscanthus, Carex, ribbons of shepherd's purse) is simply superb. The plant will take some time to establish, but what a marvel!

Planting and care
The Lychnis flos-cuculi is sown in autumn or spring in a moist soil that never dries out, well-drained, not too chalky and slightly acidic, rich, and in a sunny position. Remove faded flowers as they appear to ensure a long flowering period or to prevent spontaneous sowing. Use slug repellent to prevent attacks from gastropods, which are fond of young shoots. Divide the stump every 4 or 5 years.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
