Rosa rugosa 'Rubra,' commonly known as the Rugosa Rose, is a deciduous shrub that boasts a rugged and robust appearance. It is characterized by its dense, dark green, wrinkled foliage which provides a lush backdrop for its flowers. The leaves are quite leathery with a deeply veined texture that gives them a uniquely corrugated look. The Rugosa Rose is renowned for its stunning flowers that bloom profusely throughout the growing season. These flowers are a deep shade of pink to crimson red and are often solitary, but sometimes they form small clusters. Each blossom has a classic rose shape with a multitude of overlapping petals that create a full, cupped form. The petals have a soft, velvety texture and are known to exude a strong, sweet fragrance that can perfume an entire garden area. As the flowers mature, they give way to distinctive fruits known as rose hips. These are orange to red in color, somewhat spherical or elongated, and can be quite conspicuous against the foliage. The rose hips are not only decorative but are also valued for their high vitamin content and are used in various culinary and herbal applications. The plant has a bushy habit with sturdy stems that are often adorned with numerous sharp thorns. The prickles add a defensive quality to the shrub while also contributing to its textured appearance. Overall, the Rugosa Rose presents a hardy and attractive presence in the landscape, offering season-long visual interest with its charming flowers, attractive foliage, and colorful hips.

    The Rugosa Rose (Ru) should be watered deeply to encourage root development, particularly during its first growing season. Once established, it is quite drought-tolerant but will benefit from watering every week or two, especially in dry conditions. Generally, providing about 1 to 1.5 gallons of water for each plant is sufficient. During extreme heat or prolonged dry spells, increase watering frequency to keep the soil moist but not waterlogged. Ensure that the water is directed to the base of the plant to minimize leaf wetness and potential disease issues.

  • sunLight

    Rugosa Rose (Ru) thrives best in full sunlight for optimal blooming. It should receive at least six hours of direct sunlight daily. Plant it in an area with unobstructed access to sunlight throughout the day. Partial shade is tolerable, but the quantity and quality of the blooms may be reduced.

  • circleLife cycle

    The life cycle of Rosa rugosa 'Rubra', commonly known as the Rubra Rugosa Rose, begins with seed germination, which requires stratification through cold weather or artificial means to break dormancy. Following germination, the seedling develops into a young plant with a rosette of leaves near the soil surface, and it gradually establishes a strong root system. As the plant matures, it enters a vegetative growth phase, producing pinnately compound leaves and developing woody stems in preparation for flowering. Flowering typically occurs in late spring to early summer, showcasing fragrant, deep pink to purple flowers, which are then pollinated by insects, especially bees. After pollination, the plant produces ornamental and edible red-to-orange rose hips (fruit) filled with seeds, ensuring perpetuation of the species. The Rubra Rugosa Rose can live for many years, going through repeated seasonal cycles of growth, flowering, and dormancy during the winter months.

      Spring-Early Summer

    • Propogation: The most popular method of propagating Rosa rugosa 'Rubra', commonly known as the Rugosa Rose, is through softwood cuttings. This technique is generally performed during late spring to early summer when the new growth is still somewhat flexible. You start by selecting a healthy stem and cutting a 4 to 6-inch (approximately 10 to 15 centimeters) length just below a leaf node. The lower leaves are removed, and the cut end of the stem is often treated with a rooting hormone to encourage root development. It's then inserted into a pot filled with a well-draining soil mix. The cutting should be kept moist and in a warm environment with indirect light until roots have established, after which it can be transplanted outdoors.
