Perfect, the sunny display has advanced the colour from very dark purple (at potting) to black, matching the photo. The habit is perfect for pots that are not too trailing, and it pairs beautifully with coral morn petunias. I hope to see them again next year.

Description
The Petunia Black Ray is a sumptuously black flowering plant, with large dark trumpets where the light creates silky and velvety reflections of jet black or deep purple. It is a well-branched bushy plant, forming a luxurious dome where these surprising flowers succeed each other from summer to autumn without interruption. Its flowering enhances silver foliage, pastel or vibrant colours, creating fabulous contrasts of shades or shapes. This annual plant can quickly dress up hanging baskets, garden pots, or containers.
Our hybrid petunias all come from several plants native to the warm regions of South America. Petunia Black Ray belongs to the Solanaceae family and is closely related to ornamental tobacco, for example, and its foliage also contains alkaloids. This variety quickly forms a round and regular bushy tuft, about 40 cm (15.7 in) in height and 50 cm in diameter, with a perfect dome-shaped habit that barely droops. The plant is in flower from June to October, provided that faded flowers are regularly removed and it is regularly supplied with fertiliser. Its cup-shaped flowers are large, surprising, woven with silk and velvet of a rich and deep black, sometimes showing reflections of tin, brown, and purple. The small centre of the corolla is marked with a silver reflection. The foliage, quite hairy, has entire edges and a dark green colour, it is vigorous and healthy.
No other annual flowering plant has undergone such intense selection by breeders for such a long period. The results are impressive, as petunias rival pelargoniums in their splendour and length of flowering, as evidenced by this Black Ray variety. Place it in large pots or hanging baskets. You can also plant this petunia in flower beds to punctuate borders of plants with grey foliage such as ceraistes, cineraria maritima, or artemisias. If you want to stand out, plant several young plants to form an original ground cover at the base of plants with grey foliage such as Faassen's catmints or annual poppies in pastel colours.
Note: Please be aware that our young plants in mini-pots are professional products reserved for experienced gardeners. Upon receipt, transplant and store them in shelters (veranda, greenhouse, cold frame...) at a temperature above 14°C for a few weeks before being installed outdoors once all risk of frost has passed.

Planting and care
Plant your petunias in a sunny location or possibly in partial shade, in a sheltered spot from the wind. They need a light and humus-bearing soil and greatly appreciate fertiliser. You can plant your Petunias in a pot. They will be watered regularly. Fertiliser inputs every two weeks maintain flowering and intensify colours. Regularly remove faded flowers. Severely pinch the end of the stems to encourage the plant to branch out further.

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.
