Rose Marinette

'Marinette' is a distinctive and graceful rose, admired for its unusually delicate form and airy, almost weightless appearance. Its long, slender, pencil-like buds open into wide, semi-double flowers of soft rose pink, beautifully blended with creamy-white tones and a luminous cluster of pale yellow stamens. As the blooms mature, their colors subtly shift and soften, creating a charming, ever-changing display that gives the whole shrub the impression of being covered with fluttering butterflies. Lightly fragrant and continuously flowering through summer and autumn, it brings gentle movement and elegance to the garden. With its balanced, bushy habit and ability to blend effortlessly among other plants, 'Marinette' is an excellent choice for borders and naturalistic plantings.

DESCRIPTION OF THE VARIETY

The introduction of the English Shrub rose 'Marinette' in 1995 marked a start of the pivotal moment in the David Austin breeding program, particularly within the development of the English Musk Rose group. While the earlier English Roses of the 1960s and 1980s prioritized the dense, multi-petaled architecture of Old roses, the 1990s saw Austin exploring lightness and grace. 'Marinette' was a primary beneficiary of this aesthetic shift, offering a more naturalistic, airy form that bridged the gap between species roses and modern repeat-flowering shrubs.

The historical impact of 'Marinette' is rooted in its ability to offer a sophisticated yet understated floral display. In the broader context of modern rose cultivation, the cultivar was designed to address the needs of gardeners moving toward mixed border compositions rather than traditional, isolated rose beds. Such a balanced habit allowed 'Marinette' to serve as a versatile structural element in cottage gardens and ecological landscapes alike.

FLOWERING

The flowers of 'Marinette' start from a highly specific bud form. These buds are very long, pencil-thin that unfold to become wide, flat, semi-double flowers. This slender bud morphology is a significant differentiator from the globular or ovoid buds typical of many other English roses. The physiological transition from the tightly furled, elongated bud to the wide, flat bloom involves a rapid expansion of the petal cells, a process driven by turgor pressure and the mobilization of stored carbohydrates in the pedicel.

The flower itself is a semi-double form, the petal count sufficient to obscure the center initially but low enough to reveal the reproductive organs as the bloom matures. The number of petals varies from 15 to 25 per flower. THe flowers are medium to large sized, the average diameter of the open flowers is about 9 cm (3.5 in). The flowers appear on rather strong peduncles singly or in small clusters of 3 to 5 buds together on long stems held well above the foliage.

The colour of the petals is pink-edged but cream or white at the base, where there is a pretty circle of very pale yellow stamens. The pink parts of the petals have white streaks in them, and the petal backs are paler. If using the Royal Horticultural Society (RHS) Colour Chart as a reference, the petals typically exhibit a gradient from the white group (N155) at the margins to a pale tint of the red-purple group (62D) toward the center. The bunch of golden stamens produce abundant pollen that is easily accessible to insects due to the flower's flat, open structure. This distinguishes 'Marinette' from typical English roses which are often so densely packed with petals that they are effectively sterile for most pollinators. Although the flowers fade rather quickly to white and palest rose, the whole flower is pretty and distinct at all stages, and the bush in full flower resembles a cloud of butterflies.

Fragrance:

The fragrance of this rose is light yet pleasing with a Musk character.

PLANT

Horticulturally, the significance of 'Marinette' is underscored by its inclusion in major international rose collections. It is preserved and documented in the Europa-Rosarium at Sangerhausen, Germany, which is the world’s largest rose collection, under the official accession code ‘AUScam’. This international recognition highlights its value as a stable genetic resource within the Rosa genus. It is classified as Shrub rose, and is part of David Austin’s English Shrub Roses collection. It is also categorized by David Austin as an English Musk Hybrid.

The structure of the plant is rounded and well balanced. The mature and well established plants typically reach a height of approximately 120 cm (4 feet) and the width of about 120 - 150 cm (4 -5 feet). The canes of this rose are notably slender, which contributes to the effect of lightness and grace. These slender stems allow for a slight nodding habit when the flowers are in full bloom, particularly after rainfall, which adds to the romantic aesthetic of the plant. The bush is shrubby, graceful, upright, and nicely proportioned.

Foliage:

The foliage of 'Marinette' is medium green in colour and has matte to semi-matte surface, providing a soft background that does not compete with the delicacy of the flowers. The leaves are small and frankly susceptible to blackspot. The leaflet shape is generally ovate with serrated margins, the type of serration is medium and single.

Prickles:

There is a normal but not excessively dense quantity of the prickles on the main canes from base and on the laterals from main canes, allowing for easier maintenance and pruning.

Disease resistance:

Like many roses developed in the 1990s, 'Marinette' has moderate resistance to powdery mildew (Podosphaera pannosa) and to black spot (Diplocarpon rosae) by modern standards. The airy habit and semi-double flowers help with air circulation, but in high-humidity environments, preventative organic fungicides may be necessary.

The palest pink petals of this rose are susceptible to scorching in extreme Mediterranean climates if not provided with afternoon shade. The plant's transpiration rate is moderate, but its slender stems can lead to wilting more quickly than thicker-caned varieties under acute drought stress.

In terms of stress tolerance, 'Marinette' is adapted to a variety of climates but exhibits specific vulnerabilities. The cultivar is generally hardy to USDA Zone 5, though it thrives best in Zones 6 - 9. The plant exhibits good cane hardiness in temperate winters, though in continental climates with deep freezes, the slender stems may be more prone to desiccation or dieback if not properly mulched.

The name 'Marinette' was chosen to honor Marina Berry, the Vicomtesse Camrose, known to her friends as Marinette Marina Berry (née Sulzberger) was a prominent figure, and her nickname provided a fittingly delicate and French-sounding name for a rose of such elegance.

English Shrub Roses

Rose variety 'Auscam' / 'Marinette' originated by David Austin by crossing the English rose variety 'Ausemi' / 'Lucetta' with the English shrub rose variety 'Auscoat' / 'Redcoat'.
