GLAUCA CARMENETTA – mauve-pink park rose – Preston

Graceful and softly coloured, GLAUCA CARMENETTA brings a natural, informal charm to family gardens, forming a tall, arching shrub that works beautifully as a loose hedge or specimen in a front garden. Its once-a-year mass of mauve-pink, single flowers is followed by grey-green foliage that remains attractive, giving structure and privacy with minimal intervention. Urban-tolerant and happy even in semi-shaded, less fertile corners, it copes well with breezy, exposed sites and typical British weather provided drainage is reasonable. Own-root growth means the plant settles in steadily for a long life, developing a stable shape that suits cottage-style mixes and relaxed boundaries. With light annual pruning and straightforward watering, it offers reliable seasonal presence for busy, design-conscious gardeners who want impact rather than fuss, rewarding patient care as roots, then shoots, then full display evolve over the first three seasons into a mature, durable feature that complements both contemporary and traditional homes.


Freshly opened Carmenetta flower in soft mauve-pink.

Usage options

Target areaReasoning
Front-garden focal shrub Its tall, bushy, arching habit creates an eye-catching focal point near the house, while the mauve-pink flowers and grey-green foliage read clearly from the pavement without looking over-formal. Best for those wanting strong structure with relaxed character, particularly beginners.
Loose flowering hedge Plant in a row at 190–200 cm for a semi-transparent hedge that flowers once in summer, then holds a soft green-grey screen for the rest of the season. Minimal shaping keeps a natural outline, ideal where privacy is needed but a rigid clipped look is not, suiting homeowners.
Cottage-style back border In cottage borders, its height and arching stems form a gentle backdrop for perennials, while the simple flowers and muted colour blend easily with traditional planting. Once established, it anchors the border with low ongoing input, pleasing aesthetically focused gardeners.
Urban side-return or boundary Performs reliably in drier, nutrient-poor, semi-shaded side gardens, provided air circulation and drainage are adequate, making use of awkward spaces typical in town plots; this resilience suits busy, space-conscious urbanites.
Wildlife-friendly informal area The single flowers and occasional hips add seasonal interest and some wildlife value in a relaxed corner, especially when underplanted with pollinator plants; its once-a-year flowering keeps maintenance light, appealing to nature-minded but time-poor families.
Specimen in lawn or gravel Grown alone with space around it, the tall, arching framework and distinctive foliage create a sculptural presence that remains attractive beyond flowering, needing only occasional pruning to keep shape, attractive for design-led but practical owners.
Mixed shrub screen with drainage-conscious layout Combined with other shrubs in a slightly raised or well-drained strip, it copes calmly with damp British spells and breezier conditions, offering height without demanding complex care, reassuring cautious starters.
Background planting for small groups of roses In a group of 1–3 plants, it forms a soft, mauve-pink cloud that frames shorter roses or perennials, with its once-flowering nature simplifying deadheading as petals self-shed, making border upkeep easier for busy householders.

Styling ideas

  • COTTAGE BACKDROP – Place a single shrub at the rear of a mixed bed with lupins and foxgloves for a tall, relaxed wall of mauve-pink in early summer – ideal for cottage-garden admirers.
  • LOOSE HEDGE – Line a front boundary with evenly spaced plants, letting arching stems overlap slightly for a soft, flowering screen – suited to those wanting privacy without a formal hedge.
  • URBAN STRIP – Use along a narrow, semi-shaded side path with gravel mulch to highlight its tolerance of leaner soils – perfect for busy city gardeners making the most of side returns.
  • SCULPTURAL SPECIMEN – Give one plant a central spot in a small lawn or gravel circle so its height and grey-green foliage become a quiet focal form – for design-conscious homeowners.
  • NATURAL MIX – Combine with ornamental alliums and soft grasses in a back border to echo meadow-like planting with a gentle rose accent – attractive to relaxed, wildlife-friendly gardeners.

Technical cultivar profile
CharacteristicData
Name and registration Glauca Carmenetta, Botanical rose, shrub/park rose; ARS exhibition name ‘Carmenetta’. Unregistered cultivar, verified authenticity for pharmaROSA ORIGINAL 2-litre own-root production.
Origin and breeding Hybrid of Rosa glauca × Rosa rugosa, bred by Isabella Preston at Agriculture Canada’s Central Experimental Farm; introduced in 1923 and valued since for robust landscape use.
Growth and structural characteristics Tall, bushy shrub with upright, arching branches, 240–360 cm high and 160–260 cm wide. Moderately dense, matt grey-green foliage; moderately thorny canes; naturally informal outline.
Flower morphology Single, flat flowers in small clusters; 5–12 petals and small S-sized blooms. Once-flowering with a pronounced main flush, then cleanly self-shedding petals while hips remain on the plant.
Colour data and phenology Clear, medium-light mauve-pink with subtle lilac cast; RHS 73C–73D range. Buds deep mauve-pink, ageing to pastel pinkish-lilac and lightening faster in strong sun; non-remontant summer display.
Fragrance and aroma Soft, elegant fragrance of mild intensity; a restrained scent that complements its naturalistic character without dominating small spaces, suitable where strongly perfumed roses are not desired.
Hip characteristics Occasional spherical dark red hips, around 12–18 mm in diameter, forming sparsely after flowering. Decorative rather than abundant, adding a modest autumn accent on the arching branches.
Resistance and winter hardiness Extremely hardy to about -40 to -37 °C (RHS H7; USDA 3a; Swedish zone 6). Moderate disease resistance; may show black spot in poor air flow. Tolerates heat and moderate drought with watering.

Information about the videos
The video series is not a “seasonal showcase”; it illustrates the essence of pharmaROSA® own-root cultivation in a tangible way: how the plant is built up, what the root system is like and how the shoot system regenerates. The recordings were therefore made at different times and with plants at various stages of development, so mixed foliage levels and differing stages of growth may appear in the videos. They are not a ‘sample’ of the batch dispatched, but a visual explanation of how the technology works. The current condition of the rose available to order — typical for the given period and similar to what you can expect to receive in the parcel — is shown in the upper part of the product page.
