Description
The Decorosier OPALIA rose bush, with a coat of white flowers from spring, blooming until autumn, brings a lot of light to any setting. Its semi-double corollas of pure white blend wonderfully with all the flowers in the garden and create a beautiful contrast with the surrounding foliage. This Opalia variety is the earliest in the Decorosiers collection. Its small, shiny dark green foliage remains decorative throughout the season, and even throughout winter if it's not too harsh. An easy-to-grow rose bush in all regions, whether in a pot or in the ground, suitable for gardens of all styles and sizes!
The 'Opalia' rose bush belongs to the modern, shrub and landscape roses. Its clustered flowers come from the Polyantha rose, an old hybrid derived from Rosa multiflora and Rosa chinensis. It is a very dense bush, measuring 70 to 80 cm (28 to 32in) in height, with good coverage, in the shape of a slightly spreading dome, about 90 cm (35in) to 1 m (3ft) wide, depending on the growing conditions. Very floriferous, it produces an abundance of semi-double flowers, 4-5 cm (2in) in diameter, from May to October, in pure white, around a golden yellow stamen centre. They have no scent. They are gathered in small clusters of 10 units. Its semi-evergreen foliage is perfectly healthy, composed of small, shiny dark green leaves that cover thorny stems. This variety tolerates heat well.
The Opalia rose bush can be used in flowerbeds, borders, large spaces, slopes, or low hedges. It adapts to all soils that are not too wet and all climates, making it suitable for all regions of our country. It has dense vegetation that works wonders on a slope, hiding the ground. When planted in mass, it can border pathways and highlight flower beds. For example, it can be associated with perennial geraniums (Geranium Blue Cloud, Anne Folkard, Nimbus, Orion), bellflowers (lactiflora, rapunculoides), catmints, lavenders, snapdragons, foxgloves, or other Stachys. When left to grow freely, it forms a bush with a blurry, flowery, and cloudy shape, with a very natural appearance in front of a flowered shrub bed.
The DECOROSIERS roses are ground-covering shrub roses. They can be used in various ways: lawn borders, flowerbeds, slopes, or pots. They can be planted in all types of soil, in full sun or partial shade. They offer long and exceptional flowering periods on healthy, shiny, semi-evergreen foliage. Their qualities have been rewarded with 8 gold medals and 6 ADR labels. Naturally resistant to diseases, they do not require any treatment.
ADR ® is the label of the German Rose Breeders' Federation. The ADR designation is only given to varieties that have passed the strictest tests in the world. The plants are tested simultaneously in 10 different locations, under various soil and climate conditions for several years. The tests cover hardiness, perennial character, and flowering without any pesticide use.

Planting and care
How to plant roses. Work your soil on a 30 cm (12in) x 30 cm (12in) area, crumble the soil well and place an amendment such as bonemeal at the bottom of the planting hole. Prepare a thick mixture with water and soil. Dip your plant in the mud to coat the roots and prevent air bubbles (this is called pralinage). Position your plant in the planting hole, spreading out the roots and checking the depth: the graft point should be just above the ground. Fill with soil and gently firm it down. Prune the branches to 15/20 cm (6/8in) to stimulate growth. Create a basin at the base of the roses and water abundantly with a fine spray to eliminate air pockets and ensure the soil adheres to the roots. In very cold regions, it may be useful to mulch with leaves or turf up to 20 cm (8in) at the base of your plants. Decorosier roses do not require pruning. However, it is possible to prune them in spring by cutting back the branches by half. In summer, removing faded flowers will encourage new blooms. Naturally resistant to diseases, they do not require fungicidal treatments.
Roses are often stained or unsightly at the end of summer, but this is not a problem for their development. These stains are not harmful to the rose, it is a natural phenomenon.

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.
