Description
The Petunia Surfinia 'Heavenly Blue' produces flowers of a heavenly blue colour, a rare colour in the garden that is highly appreciated by professional and amateur gardeners. The exceptional colour of this flowering plant is not its only quality. The plant combines vigorous growth, a unique habit, both compact, upright, and trailing, and excellent resistance to adverse weather conditions. Its unparalleled floribundity and beautiful heat resistance make it naturally suitable for hanging baskets. A generous annual plant, stunning and easy to grow, almost maintenance-free!
Petunia belongs to the Solanaceae family; it is closely related to ornamental tobacco, for example, and its foliage also contains alkaloids. These annual, biennial or frost-tender perennial plants are mostly grown as annuals and all originate from the warm regions of South America. Petunia Surfinia® is a relatively recent sterile hybrid of petunia, with a trailing habit rather than an upright one, making it a magnificent plant for hanging baskets. It was created in Japan and is also distinguished by its beautiful and very long flowering period.
Petunia surfinia 'Heavenly Blue' forms a vigorous rounded, dense, bushy, and trailing clump, with trailing and fuzzy stems that cascade down 60 cm. The plant flowers from May-June to October, provided it is regularly supplied with water and fertiliser. Its cup-shaped flowers are of a good size, initially slightly tinged with mauve when they first open and then a true light blue colour, centred on a darker throat. They are tightly packed together on a well-furnished foliage. The hairy leaves are ovate and pointed, with entire margins and a dark green colour, vigorous and healthy. This variety exhibits an exceptional habit and requires very little maintenance, as its sterile flowers easily drop off by themselves.
No other flowering annual plant has undergone such intense selection by breeders for such a long period. The results are impressive, as petunias compete with pelargoniums in terms of splendour and length of flowering, as demonstrated by this variety of Surfinia 'Heavenly Blue', a little piece of sky to hang everywhere on the terrace or balcony. Plant it in large pots or hanging baskets, creating a perfect contrast with Surfinia petunia varieties 'Deep Red' or 'Purple'. You can also plant it in borders, to punctuate gray-foliaged plants such as ceraistes, cineraria maritima, or artemisias. If you want to stand out, plant several plants to create an original ground cover at the base of plants such as Nepeta faassenii or annual poppies in pastel colors.
Green plants measuring 4 to 8cm (3.1 in) in trays of 5 small plugs with a diameter of 2.8 cm (0.8 in) and a height of 4 cm (1.6 in), labelled separately. Our plants are at least eight weeks old and strong enough to be planted in the ground.
Note: Please be aware that our young plants in plugs are professional products intended for experienced gardeners: upon receipt, transplant and store them under cover (veranda, greenhouse, cold frame...) at a temperature above 14°C for a few weeks before planting them outdoors once all risk of frost has passed.

Planting and care
You can plant your petunias in the ground or in pots. If you want to plant them in the ground, wait until the last heavy frosts have passed (Surfinia petunias can tolerate a late frost). In the meantime, you can pre-cultivate them in pots in a warm and bright place to accelerate their growth. Plant your petunias in a sunny location sheltered from the wind. They need a light and humus-rich but mainly well-drained soil. Do not water them too much at the beginning of their growth as they are sensitive to excess moisture. They tolerate drought well but will need regular watering during hot summer temperatures. Very floriferous and fast-growing, they are hungry plants. We recommend feeding them with a liquid fertiliser for surfinias once or twice a week during the growth period. Remove faded flowers and dry leaves as they appear to keep them looking good and extend the flowering period.

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.
