Description
Mexican Catchfly Jack Flash is a herbaceous perennial plant of the family Caryophyllaceae, which differs from other varieties by its red star-shaped blooms.
This variety is sometimes distributed under the synonym: Silene laciniata Starburst.
The light green lanceolate leaves are slender and delicate, measuring 2 to 4 cm long and 0.5 cm wide. Foliage is dense. The numerous flower stems get tangled up and intertwine, forming a light, airy clump reaching a total height of 45-60 cm.
The solitary flowers are borne on slender aerial stems and are surprisingly shaped into bright red stars that are deeply cut into 20 points. The centre of the flower is yellow-orange and is outlined with a touch of white. Lavish stamens emerge from the centre and reinforce the star-like shape of the blooms. The flowers, which are 2 to 3 cm in diameter, are repeat bloom uninterruptedly from June to the end of August. Their unique shape is an immediate eye-catcher.
Silene laciniata Jack Flash is easy to grow and has no special requirements concerning the quality of the soil. Even if it prefers a sunny position, it can tolerate light shade. It is an original plant that is easy to introduce in the garden in the middle of a perennial bed or to grow in a pot on the terrace where it will undoubtedly be admired by all.
The first flowers appear quickly in the first year from seed.

Planting and care
Sow Mexican Catchfly Jack Flash from March to May in a seed tray. Use a good quality compost that you will sift on the surface to allow the seed to bind to the growing medium. Before sowing, lightly tamp down the soil with a small plank of wood. Broadcast sow your seeds. Cover the seeds with a fine sprinkling of topsoil or vermiculite, tamp down lightly and water generously with a fine spray. Place your tray in the light, without direct sunlight, at a temperature of 15°c to 20°c.
Seed emergence takes 14 to 21 days. As soon as the seedlings can be handled, transplant them into 7 cm pots. Keep the soil moist during growth, but not excessively so. Then, 15 days before planting them out in their final positions, start to acclimatize them gradually until a temperature of 15°c is reached.
End of May, beginning of June, the temperature in the garden will be warm enough to install your young plants. Choose a site with plenty of sunshine. Add a good shovelful of compost to each planting hole. Space your plants 30 cm apart.
Regularly remove faded flowers to keep plants tidy looking and encourage bloom renewal.

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.
