Japanese Rose (Rosa rugosa), also known in horticultural circles as simply ‘rugosa’, has a similar appearance to native dog rose. It arrived in the UK in 1796 but was first recorded in the wild in 1927 due to escape from horticulture.
WARNING
Japanese rose is listed under Schedule 9 to the Wildlife and Countryside Act 1981 with respect to England and Wales. As such, it is an offence to plant or otherwise allow this species to grow in the wild.It is recommended that this plant is controlled or eradicated, and you have a duty of care to prevent its spread from your property. You must handle and dispose of the plant in accordance with strict guidelines and legislation. Contact us, we can help.

Japanese Rose Identification
About - Japanese Rose
Japanese rose suckers freely and forms dense, wide-reaching thickets that can out-compete native species. It’s commonly grown in gardens and amenity planting, such as in parks and around retail centres. The flowers are white to pink and the resulting hips are large and orange or red. The elliptically shaped leaves are alternate and of a leathery texture.
It typically spreads by escaping from gardens or from material thrown out from gardens. Vegetative spread is the main form of propagation and is either root-borne or stolon-borne suckers. The hips are attractive to birds and animals which can facilitate dispersal of the seeds. Its distribution in the wild is increasing. Plants are easily identifiable from their showy purplish-pink flowers. It particularly causes problems in dune habitats and along coastal grasslands. It can form dense stands, potentially at the expense of ecologically important native plants. Key features include:
- White – red flowers, usually bright purplish-pink
- Scented flowers around 6-9cm across, usually solitary
- Upright stems with many slender thorns
- Fruit is round, red and 1.5-2.5cm across
- Leaves divided, shiny green on upper side
Dangers - Japanese Rose
The effects of Rosa rugosa on native flora and fauna are generally negative by reducing the number of native species present at the invaded sites. Rosa rugosa displaces the natural flora of beach and dune vegetation affecting both common and rare species.
Typical dune species like Arenaria serpyllifolia, Empetrum nigrum, Festuca rubra ssp. arenaria, Galium mollugo, Poa pratensis ssp. subcaerulea, Veronica arvensis, Viola tricolor as well as mosses and lichens decline. The strong reduction of the species diversity is caused by the shading effect of Rosa rugosa.
When the local plant life is displaced the animal species that depend on these plants are also threatened (such as butterflies that lay the eggs only on certain seashore plants). Moreover, it was shown that the biological invasion of Rosa rugosafacilitates other non-native species probably in a self-preventing system of positive feedback circles.
Japanese Rose UK
Japanese rose is widely distributed throughout Scotland, Wales and England, but less so in Ireland. In the UK it occurs in hedgerows, road verges, rough and waste ground and more frequently by the sea in sand dunes, shingle and cliffs. Occasionally, it forms hybrids with native species.
