As a rose variety that has attracted much attention in recent years, Marilyn Monroe Rose has won the favor of many gardening enthusiasts for its elegant flower shape and unique colors. As a British rose variety cultivated by David Austin Company, it shows significant advantages in ornamental and cultural characteristics, but also has some noteworthy limitations. An in-depth understanding of the advantages and disadvantages of this variety will help gardening enthusiasts make reasonable choices based on actual needs.
- - Excellent ornamental characteristics demonstrate the value of the variety-The most eye-catching advantage of Monroe rose lies in its excellent ornamental value. The flower diameter can reach 10-12 cm. The typical cup-shaped flower shape is full and round. The number of petals is between 70-80, which are closely arranged to present a stunning sense of hierarchy. The color presents a soft peach orange color, which gradually turns to cream pink as the flowers bloom. This unique color change process gives the plant a special ornamental charm. The flowering period can last from May to October. Under suitable conditions, repeated flowering can be achieved in multiple seasons. The flowering period of a single flower is maintained at 7-10 days, and the viewing duration is satisfactory. The aroma performance is another highlight of Monroe roses. The flowers exude a strong fruity aroma, mixed with the sweet aroma of citrus and peach. The aroma intensity can reach 4.5/5 points (International Rose Aroma Rating Standard), which can be clearly perceived within a range of 10 square meters, making it particularly suitable for planting in leisure areas or in a landscape location close to your living room. - - Growth habits adapt to a variety of cultivation environments-From the perspective of cultivation adaptability, Monroe rose shows a medium plant type, with a mature plant height of about 1.2-1.5 meters and a crown width of 0.9-1.2 meters. This moderate body shape makes it suitable for both garden cultivation and large-scale container cultivation. Disease resistance test data showed that the resistance to black spot was 7.9/10, and the resistance to powdery mildew was 8.2/10 (American Rose Association standard), which was significantly better than traditional rose varieties. Cold resistance reaches USDA5-9 areas, can withstand low temperatures from-23 ° C to-29 ° C, and can wintering in the open air in most areas of my country. The branch characteristics show a good natural shape, new branches have strong germination ability, and the annual growth can reach 40-60 cm, which allows the plant to quickly form a plump plant type. It is worth mentioning that its upright stems (about 6-8mm in thickness) can well support large flowers, and the lodging rate is less than 15%, which is significantly better than similar large flower varieties. - - Points to pay attention to in cultivation management-There are several key points in the daily management of Monroe roses. In terms of light demand, direct light of no less than 6 hours per day is a necessary condition to ensure the number of flowers. In an environment of insufficient light, the number of flowers may be reduced by 40-60%. Soil adaptability is wide, but loose loam soil with pH 6.0 -6.5 is the best, and the groundwater level should be lower than 80 cm to avoid root rot. It is recommended to use slow-release fertilizer with the ratio of "N-P-K=3-1-2" for fertilization, which is supplemented once a month during the growing season. Adding phosphorus and potassium fertilizers before flowering can improve the quality of flowering. Pruning technology is crucial to maintaining plant type. It is recommended to carry out strong shearing in early spring every year, retaining 3-5 main branches and 2-3 full buds per branch. Cut off residual flowers in time after blooming in summer, and retain buds that grow outward to promote ventilation. It is worth noting that this variety is sensitive to pruning, and improper pruning may cause growth to stop for 2-3 weeks. - - Main limitations in practical application-Monroe roses have several noteworthy shortcomings. In a high temperature and high humidity environment (daily temperature continues to be>32°C and humidity>75%), the edges of petals are prone to scorch, and the viewing period may be shortened by 30-40%. Flowers have average rain resistance. Continuous rainfall will cause brown spots on the outer petals, which seriously affects the ornamental value. Some growers have reported that iron-deficient yellow leaves are prone to appear when cultivated in alkaline soil (pH>7.5) and require regular application of iron chelate to correct them. From the perspective of growth characteristics, young seedling growth is relatively slow and usually takes 2-3 years to reach the full flowering stage, which may test the patience of growers. Another practical problem is that its strong aroma may attract pests such as thrips. Monitoring data shows that the thrips infestation rate of Monroe rose is 20-25% higher than that of ordinary varieties, and early prevention and control need to be strengthened. - - Comprehensive evaluation and application suggestions-Overall, Monroe rose is particularly suitable for horticulturists who pursue ornamental quality. It is recommended to plant it in the center of a sunny and well-ventilated courtyard, or as a material for aromatic hedges. Pair it with blue-purple plants (such as sage and veronica) for excellent color contrast. For balcony growers with limited space, it is recommended to choose large containers more than 60cm and pay attention to strengthening summer shading measures. Compared with similar varieties, Monroe rose is superior to 'Peace' rose in disease resistance and aroma performance, but is slightly inferior to 'Red Fan' in heat resistance. Its unique retro pattern provides an interesting contrast with the modern garden style and is ideal for creating an English garden atmosphere. If growers take preventive measures to address their weaknesses, this variety will continue to provide satisfactory gardening enjoyment.
