Description
Viola wittrockiana 'Ultima Radiance F1 Mix' bicolour pansies are fascinating, as they change colour depending on temperature and exposure. They boldly display original and varied shades, almost fluorescent, and enhanced by a small white and golden heart, making their dazzling blooms impossible to ignore. These biennial plants are compact, vigorous, and floriferous in autumn and spring, easy to grow in humus-rich and moist soil, in any site.
Garden pansies, sometimes called Swiss giant pansies, are hybrids grouped in the Viola x wittrockiana group. They belong to the violet family and are usually grown as annuals or biennials, although they are theoretically perennials but short-lived. The 'Ultima Radiance F1 Mix' variety produces branched plants that quickly form compact clumps, with a slightly spreading habit, reaching 20 cm (7.9 in) in height and 20 to 30 cm (11.8 in) in width. They bloom in spring and autumn. The 'Radiance Mix' pansies offer medium-sized flowers, 4 to 5 cm (2 in) in diameter, with open blooms. Invariably bicoloured, the flowers display shades ranging from blue to violet, pink, red, orange and white, paler or darker and more or less contrasting depending on the temperature and/or their exposure. All petals show a large central area in a contrasting shade, often lighter, widely bordered by a deeper, extremely bright shade. The base of the petals is adorned with a beautiful bright yellow spot from which beautiful black 'whiskers' radiate. The medium green leaves are elliptical and broadly crenate.
If you love them in the garden you will greatly appreciate them in window boxes, to enjoy while keeping warm inside. You can combine pansies with primroses, wallflowers, grape hyacinths, daisies, and even with grasses like Japanese sedge for a graphic effect with a contemporary feel. Pair them with heucheras and tulips. The bluish-green of glaucous fescues also enhances their beauty.
The petals of pansies are edible, and their colours will bring a touch of originality to your salads and pastries. For this purpose, think of growing them as you would your vegetables - in the most natural way possible.
Please note that our young plants in mini-plugs are professional products intended for experienced gardeners: upon receipt, transplant them as soon as possible into pots, or directly into flower beds.

Planting and care
Very floriferous and fast-growing, the pansies in the 'Ultima Radiance Mix' are hungry and appreciate a sunny or partially shaded site, or even one that is shaded in the afternoon. They thrive in a humus-rich, neutral to acidic, moist and fertile soil. Feed them with a liquid fertiliser for containers once or twice a week during the growing season. Water regularly but not excessively. Regularly remove faded flowers to encourage new flowering.

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.
