Rugosa Rose (Rosa rugosa) 

The Rugosa Rose (Rosa rugosa) is in the Rose Family (Rosaceae) and the order Rosales. Rosa is Latin for rose. Rugosa is Latin for shriveled and refers to the wrinkled appearance of the leaves. It is a shrub that can grow to six feet (1.8 meters). The flowers are usually red but can be white, as shown in the photograph below, or even violet.  They are up to three inches (7.5 centimeters) wide with five petals and five narrow sepals as shown in the photograph above. There are numerous yellow to white stamen and pistils in the center of the flower. This plant flowers from June to September.

White Rugosa Rose

The leaves are compound, pinnately divided into numerous (usually seven), toothed, wrinkled, ovate leaflets arranged opposite along the leaf stalk with the one leaflet extending from the end of the leaf stalk. The compound leaves are up to six inches (15 centimeters) long.

The fruit is a fleshy, red hip about one inch (2.5 centimeters) in diameter, usually with the sepals still attached and containing light brown seeds. A hip is a mass of somewhat dry flesh that is associated with the fruits of the Rose Family.

The root system is rhizomic.

This plant is noted for its ability to stabilize sandy soils and is very common on Mount Desert Island along roadsides and in sandy areas. However, only one example of this plant was observed on the eastern shore of French Hill Pond.
