rose [Grouse]


The Rosa Grouse, commonly known as 'Korimro', is a type of rose that presents a delightful visual appeal. The plant is adorned with an abundance of flowers that exhibit a breathtaking blend of colors. Typically, these blooms are rich in hues, showing off shades that can range from deep pinks to gentle pastels, depending upon the variety. The flowers themselves are classically shaped with a full, cupped form that invites admiration. Their petals unfurl elegantly and may show some variation, with outer petals being slightly lighter or deeper in color compared to those at the heart of the bloom. Each flower is comprised of numerous layers of petals, which overlap in a symmetrical fashion to create a rosette-like appearance that is deeply associated with roses. Leaves of the Rosa Grouse are glossy, adding a lush backdrop to the vivid floral display. They are typically a vibrant green color, which contrasts beautifully with the blooms. Often, the foliage has a leathery texture, contributing to the overall hardiness of the plant. The stems of this rose variety can be long and are usually armed with thorns that vary in size. These thorns act as a defense mechanism, protecting the plant from hungry herbivores and providing some support for the heavy blooms. Overall, the Rosa Grouse 'Korimro' is a captivating sight with its richly colored flowers, lustrous leaves, and robust structure. It is a popular choice for gardens due to its ornamental beauty and the classic charm that roses bring to any landscape.

  • water dropWater

    The Rosa Grouse, commonly known as the shrub rose, should be watered deeply and infrequently, promoting strong root growth. Aim to water the plant once a week with about 1-2 gallons during the growing season, depending on weather conditions and soil type. In hot, dry periods, you might need to water twice a week, while in cool, moist conditions, once every two weeks may be sufficient. The goal is to maintain even moisture in the soil but allow it to dry out slightly between waterings. Always avoid overhead watering to reduce the risk of leaf diseases, and instead water directly at the base of the plant.

  • sunLight

    Shrub roses thrive in full sunlight, so the Rosa Grouse should be placed in a spot where it receives at least 6 to 8 hours of direct sun per day. Avoid locations that are overly shady or have filtered light as this can impact the plant's flower production and overall health. Morning sun is particularly beneficial as it helps to dry dew off the leaves, reducing the risk of fungal diseases.

  • thermometerTemperature

    Shrub roses prefer moderate temperatures and are hardy in a range of conditions. The Rosa Grouse can typically survive in temperatures as low as 20°F and as high as 90°F, but it thrives best when daytime temperatures are between 65°F and 75°F. It is important to protect the plant from extreme cold by applying mulch around the base and from intense heat by ensuring it has adequate water and air circulation.

  • scissorsPruning

    Pruning the Rosa Grouse encourages healthy growth and abundant blooming. In the early spring, before the plant breaks dormancy, remove any dead or diseased wood, and thin out crowded areas to increase air circulation. During the growing season, deadhead spent flowers to promote more blooms. An annual hard pruning of about one-third of the plant's size can be done in late winter to maintain its shape and vigor.

  • circleLife cycle

    The Rose 'Kordes Moonlight' (Rosa Grouse = 'Korimro') life cycle begins with germination from a seed, although commercially, they are more commonly propagated by grafting or cuttings to maintain the varietal characteristics. The plant then enters a vegetative stage where foliage, roots, and stems develop rapidly. As it matures, the rose bush enters the flowering stage in late spring to early summer, producing fragrant, yellow blooms that attract pollinators. After pollination, if it occurs, hips (fruits) may form, containing seeds for potential new plants. The plant goes through a period of dormancy in winter, losing its leaves and conserving energy, before resuming growth in the spring. Throughout its life, the rose bush will experience cycles of growth, flowering, and dormancy annually, with proper care enabling it to live for many years.

      Spring to summer

    • Propogation: The Rosa Grouse 'Korimro', commonly known as the Grouse Rose, is typically propagated by semi-hardwood cuttings. The most popular method of propagation for this plant involves taking cuttings that are approximately 6 to 8 inches (15 to 20 centimeters) in length from healthy, disease-free parent plants. These cuttings should be taken during the summer months when the plant is actively growing. The bottom of each cutting should be dipped in a rooting hormone to encourage root development and then planted in a well-draining soil mix. Keeping the cuttings in a humid environment and ensuring they have consistent but not excessive moisture will help them to establish roots and grow into new plants.
