A compact and spreading variety, ideal for borders, planters or hanging baskets. Its sky-blue flowers appear very early, from just 9 to 10 weeks after sowing, even when days are still short. This tender perennial, grown as an annual, withstands temperatures down to approximately -3°C. It prefers a sunny to partially shaded position and well-drained soil, tolerating challenging garden conditions. To extend its flowering until the first frosts, it is advisable to regularly remove faded flowers.

Description
Petunia Flashforward™ Sky Blue Seeds (coated seeds) allow you to grow this tender perennial with ultra-early and abundant flowering, ideal for brightening up borders, containers or hanging baskets at low cost. This hybrid cultivar stands out for its low, spreading and trailing habit, quickly forming a dense carpet of small, bright sky blue flowers. Perfect for container growing as well as in open ground, it adapts to urban gardens as well as large borders. Sow under cover from February-March.
Petunia Flashforward Sky Blue is a horticultural cultivar from the Solanaceae family, also called trailing petunia or cascade petunia. It is a hybrid developed by Syngenta Flowers, distinguished by its exceptionally early and abundant flowering. Native to South America, the Petunia genus is primarily native to Argentina, Brazil and Uruguay, where it grows in open, sunny habitats. The Flashforward Sky Blue cultivar has a spreading and slightly trailing habit, forming a dense carpet of small sky blue flowers. In open ground, it reaches a height of 20-25 cm and spreads 45-60 cm, while in containers, its dimensions are slightly reduced. Its growth is rapid, with flowering beginning approximately 9-10 weeks after sowing. The trumpet-shaped flowers measure 2.5-3.8 cm in diameter and are sky blue. They appear from early summer and continue until the first frosts. The leaves are ovate, medium green, and arranged alternately along the slightly sticky stems. The root system is fibrous and shallow, suited to well-drained soils. An interesting fact: petunias are often used as companion plants in vegetable gardens for their ability to repel certain harmful insects, such as aphids and tomato hornworms.
Petunia Flashforward Sky Blue thrives in sun, sheltered from wind. Plant it in rich, light, well-drained soil or substrate. Its cultivation is easy, but it is thirsty for water. To encourage and support its long flowering period, it is advisable to apply a potash-rich fertiliser, especially in pots and containers, which will promote the appearance of new flowers. Flashforward™ Sky Blue spreads like a light blanket over borders, slopes or hanging baskets, offering a soft sky blue cloud to the garden. It looks good with silver foliage from Helichrysum petiolare or the frothy swirls of Lobularia maritima ‘Snow Crystals’ (sweet alyssum), with which it shares a preference for full sun and temporary dryness.

Planting and care
Sow Petunia Flashforward Sky Blue from February to April on the surface of a good sowing compost and gently firm. Lightly cover the seeds with a fine layer of vermiculite or sieved compost. Place the tray in a propagator (or enclose it in a polythene bag) or above a radiator, at a temperature of 21 to 25°C. Keep the soil moist but not waterlogged. Light aids germination, which usually takes 10 to 21 days.
When the young petunia plants are large enough to handle, proceed with transplanting. Gradually acclimatise the young plants to cooler conditions until they are strong enough to be planted outside, once all risk of frost has passed. Transplant into well-drained soil at a distance of 30 cm or grow them in pots or containers.

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.
