Multiflora Rose Rosa multiflora var. cathayensis (Ra)
ABOUT
Rosa multiflora, commonly known as multiflora rose, is characterized by its dense and thorny habit. It boasts a prolific display of clusters of small, fragrant flowers, which may range in color from white to pink, often with a lighter center. The blooms typically appear in late spring to early summer and can blanket the bush, creating a stunning visual effect. The leaves of the multiflora rose are lush and compound, composed of several small, oval-shaped leaflets arranged along a central stem. They are usually bright green, providing a contrasting backdrop to the delicate blossoms. The leaflets have toothed edges, which add to the textured appearance of the foliage. The stems of the plant are long and arching, and they are covered with sharp thorns that can pose a challenge to gardeners or anyone handling the plant. These thorns, alongside the dense growth of the plant, can make multiflora rose very difficult to control once established. After the flowering period, the plant produces small, red-to-orange, round or oval-shaped fruits, commonly known as hips. These hips persist into the winter and provide food for a variety of wildlife, while also adding winter interest to the landscape where the plant is present. The multiflora rose is often found forming thickets and its vigorous growth habit allows it to spread rapidly, which is why it is frequently used as a living fence or for erosion control. However, this same trait also makes it an invasive species in some regions, where it can crowd out native flora and alter ecosystems.

WaterFor the Rambler Rose, establish a deep and thorough watering schedule, ensuring the plant receives about 1 to 2 gallons of water weekly. During the growing season in spring and summer, particularly in dry spells, it may be necessary to water twice a week. Water directly at the base of the plant to minimize wetting the foliage, which can lead to disease. In the cooler fall and winter months, reduce watering frequency, as the plant's water needs will decrease. Ensure that the soil drains well to avoid waterlogging, which can harm the roots.
LightThe Rambler Rose thrives best in full sunlight exposure. Ideally, plant it in a location where it can receive at least six hours of direct sunlight each day. They can tolerate some light shade, especially in hotter climates, but too much shade will reduce bloom production and can make the plant more susceptible to diseases.
TemperatureRambler Roses prefer temperate conditions and operate best when the temperature ranges between 60°F to 70°F. However, they are quite hardy and can survive in temperatures as low as 15°F and as high as 90°F. Protection from extreme cold and heat is beneficial for the plant's health and flowering ability.
PruningPruning the Rambler Rose is essential to maintain its shape, remove deadwood, and promote more vigorous growth. The best time to prune is in late winter or early spring before new growth starts. Prune out any dead or diseased stems and thin overcrowded areas to improve air circulation. Repeat-flowering varieties can also be lightly pruned after the main bloom to encourage a second flush of flowers.
CleaningAs needed
SoilThe best soil mix for the rambler rose (Rosa multiflora var. cathayensis) is a well-draining loamy soil with some organic matter like compost or aged manure worked in. A balanced pH level around 6.0 to 7.0 is ideal for this rose variety to thrive.
RepottingRambler roses like Rosa multiflora var. cathayensis do not typically require frequent repotting. They should be repotted or transplanted only when they outgrow their current space or every 2-3 years to refresh the soil.
Humidity & MistingRambler roses prefer moderate ambient humidity. Aim to maintain a humidity level of around 40% to 60% for healthy growth, avoiding excessive moisture that can lead to disease.
Suitable locationsIndoor
Place in bright, direct light and keep well-watered.
Outdoor
Plant in full sun, well-drained soil, and water regularly.

Life cycleThe life cycle of Rosa multiflora var. cathayensis (Chinese Multiflora Rose) begins with seed germination, where the seeds require a period of cold stratification to break dormancy. The seedlings emerge and establish themselves, producing a rosette of leaves in their first year. As the plant matures, it develops long arching canes with compound leaves, thorns, and clusters of small, fragrant flowers typically in late spring to early summer. Following pollination by insects, the flowers develop into small red hips (fruit), containing the seeds for the next generation. These hips persist on the plant into winter, providing food for wildlife, and contributing to seed dispersal. The plant can also spread vegetatively through root suckers, forming dense thickets over time.
PropogationPropogation time
Spring to early summer
Rosa multiflora var. cathayensis, commonly known as the multiflora rose, is often propagated by softwood cuttings, which is one of the most popular methods due to its effectiveness. This technique is best performed in late spring to early summer when the plant's new growth is mature enough yet still tender. Cuttings should be about 6 to 8 inches long with several leaves attached, and the cut should be made just below a leaf node. The lower leaves are removed and the cutting is dipped in rooting hormone to enhance root development. The treated cutting is then inserted into a well-draining soil mix, ensuring at least two nodes are beneath the soil surface. To maintain high humidity, a plastic cover can be placed over the pot, and it's important to keep the soil consistently moist without being waterlogged. In a few weeks, the cuttings will establish roots and can be transplanted to a permanent location.
