Identification

Nutka Rose is easily recognizable once you know its distinctive characteristics, which set it apart from other native and non-native roses in its range. This vigorous shrub combines classic rose features with specific adaptations that reflect its diverse native habitats.

Growth Form & Size

Nutka Rose typically grows 3-10 feet tall, forming dense, suckering colonies that can spread 6-8 feet wide or more. The growth form varies from low, spreading thickets in harsh mountain conditions to tall, upright shrubs in protected forest edges. The plant develops multiple stems from a spreading root system, creating the dense, impenetrable thickets characteristic of the species in optimal conditions.

Stems & Thorns

The stems are woody, ranging from reddish-brown to gray-brown, and are armed with stout, slightly curved thorns that are typically paired at the nodes. The thorns are substantial — about 1/4 to 1/2 inch long — and help distinguish Nutka Rose from thornless species like Thimbleberry. Young stems may appear more reddish, while older canes develop gray-brown bark that may peel slightly.

Leaves

The compound leaves are palmately divided into 5-7 oval leaflets (occasionally 3-9), each 1-3 inches long with serrated margins. The leaflets are arranged on short petioles and have a distinctive blue-green to gray-green color that helps identify the species. Each leaflet is oval with a pointed tip and fine teeth along the margins. The stipules at the base of each leaf are prominently winged and often reddish, providing another identification marker.

Flowers

The flowers are among the most spectacular features of Nutka Rose and are key to identification. Individual blooms are large — typically 2-3 inches across — with 5 bright pink petals (occasionally white) surrounding a prominent center of yellow stamens. The flowers usually appear singly at the tips of branches, though occasionally 2-3 flowers may cluster together. The blooms are notably fragrant and appear from late May through July, depending on elevation and latitude.

Fruit (Rose Hips)

The rose hips are distinctive and provide excellent winter identification. They are round to pear-shaped, about 1/2 to 3/4 inch in diameter, and ripen from green to bright red or orange-red. Unlike some rose species, Nutka Rose hips are smooth (lacking bristles or prickles) and topped with persistent sepals that remain attached through winter. The hips contain numerous small, hard seeds surrounded by irritating hairs.

Native Range

Nutka Rose boasts one of the most extensive native ranges of any North American rose, stretching across diverse climatic and geographic regions from Alaska to New Mexico and from the Pacific coast to the Great Lakes. This remarkable distribution demonstrates the species’ exceptional adaptability and ecological success across varied environmental conditions.

In the Pacific Northwest, Nutka Rose is found throughout Oregon, Washington, northern California, and into British Columbia and Alaska. The species extends eastward across the northern Rocky Mountains through Idaho, Montana, Wyoming, and Colorado, with isolated populations reaching as far east as Michigan in the Great Lakes region. Southern populations occur in Utah, New Mexico, and high-elevation areas where conditions remain suitable for this cool-climate adapted species.

This vast range reflects the species’ evolution during the Pleistocene, when cooler climates allowed continuous distributions across what are now fragmented habitats. Today’s populations represent both continuous ranges in suitable habitat and relict populations persisting in favorable microclimates within otherwise unsuitable regions.

Within its native range, Nutka Rose typically establishes in habitats that provide the specific environmental conditions it requires for optimal growth and reproduction. These habitat preferences have evolved over thousands of years and represent the species’ ecological niche within Pacific Northwest ecosystems.
