Yellow Rose of Sulfur Rosa 'Dupontii' (S)
ABOUT
Rosa 'Dupontii' (S), commonly known as a type of rose, typically showcases stunning flowers that captivate onlookers with their beauty. The blooms are usually known for their layered petals ranging in hues from deep velvety crimsons to soft, romantic pinks, depending on the variety. Some may flaunt vivid yellows or pure, snowy whites. The petals can have a delicate, velvety texture and may exude a sweet, enchanting fragrance that perfumes the air, attracting both humans and pollinators alike. The foliage of the rose lends a lush backdrop to its blossoms, with leaves that are typically glossy and dark green. The leaves are often oval-shaped with a pointed tip and may have a serrated edge. This greenery is arranged alternately along the canes, which may bear thorns. These thorns can vary in size and sharpness, and they serve as both protection for the plant and a support for climbing varieties which may hold onto other structures. Flowering period of roses can vary greatly, with some blooming just once a year while others may repeat their floral display several times throughout the growing season. During these blooming periods, a rose bush can be covered with flowers, creating an eye-catching spectacle. Apart from their pleasing aesthetic, roses are also commonly associated with various cultural and symbolic meanings, ranging from love and affection to remembrance and purity, which adds another layer of significance to their presence in gardens and floral arrangements.

ToxicityTo humans
The Rosa 'Dupontii', commonly known as the rose, is not considered toxic to humans. Usually, roses don't cause poisoning when touched or ingested. However, it's important to note that all rose varieties have thorns that can lead to physical injury if handled improperly. Also, in some very rare cases, people might be sensitive or allergic to rose petals, which could potentially cause mild irritation or an allergic reaction. It's always good practice to handle plants with care to avoid any unnecessary risks.
To pets
The Rosa 'Dupontii', commonly referred to as a rose, is generally considered non-toxic to pets. Roses are not known to cause serious poisoning in dogs, cats, or other domestic animals if ingested. Similar to the effects on humans, the primary concern with roses and pets is the physical danger posed by the thorns, which can cause injuries. Ingesting a large amount of rose material could potentially lead to gastrointestinal upset, evidenced by symptoms like vomiting or diarrhea, mostly due to the indigestible nature of the plant material rather than chemical toxicity. It's still wise to prevent pets from ingesting or playing with roses to avoid thorn injuries and any digestive discomfort.

WaterThe Rosa 'Dupontii', commonly known as the Dupont Rose, should be watered deeply and infrequently to encourage strong root systems. During the growing season, it is ideal to provide about 1 gallon of water per week, making sure to water the base of the plant to reduce the risk of leaf diseases. Always check the top 2 to 3 inches of soil for dryness before watering. In hot, dry periods, water twice a week, while in cooler or rainy climates, adjust to less frequent watering to prevent waterlogging. Overhead watering should be avoided to minimize the potential for fungal diseases.
LightThe Dupont Rose thrives in full sunlight, requiring at least 6 hours of direct sun daily for optimal growth and blooming. An east or west-facing spot is suitable, ensuring that the rose gets morning light and some afternoon shade in extreme heat. Too much shade can lead to sparse blooms and increase susceptibility to pests and diseases.
TemperatureDupont Roses prefer temperate climates with temperatures between 65°F and 75°F for vigorous growth. They can typically handle temperature fluctuations, with a minimum survival temperature around 20°F and a maximum of 90°F. To ensure a healthy plant, avoid placing it in areas of extreme cold or heat that go beyond these thresholds.
PruningPruning is essential for the health and vitality of the Dupont Rose, typically done in late winter or early spring before new growth starts. Prune to remove dead or diseased wood, to shape the plant, and to improve air circulation, which helps prevent fungal diseases. Pruning should be done yearly, cutting back about one-third of the plant's height, and always cutting at a 45-degree angle above outward-facing buds.
CleaningAs needed
SoilThe best soil mix for growing Rosa 'Dupontii', commonly known as the Dupontii Rose, includes well-draining loamy soil enriched with organic matter like compost or rotted manure. The soil pH should be slightly acidic to neutral, ranging from 6.0 to 7.0.
RepottingDupontii roses generally do not need to be repotted often since they are typically grown outdoors. However, if grown in containers, they should be repotted every 2 to 3 years to refresh the soil and accommodate the root growth.
Humidity & MistingDupontii roses prefer moderate to high humidity levels but are adaptable to a range of humidity conditions as long as they are not waterlogged. They can thrive in average garden humidity.
Suitable locationsIndoor
Ensure bright indirect light and adequate air circulation for indoor Dupontii Roses.

Life cycleThe Rosa 'Dupontii', commonly known as a variety of Old Garden Rose, begins its cycle when a seed germinates in the soil, given the right conditions of warmth and moisture. The seedling then emerges, developing primary leaves and a root system. As it matures, the plant undergoes vegetative growth, forming a sturdy stem and lush foliage through photosynthesis and nutrient uptake. The plant reaches maturity when it starts to bloom, producing fragrant yellow flowers that attract pollinators and set the stage for pollination and the formation of hips, which are the fruit of roses containing seeds. After the flowering phase, the plant may enter a period of dormancy, especially in colder climates, conserving energy for the next growing season. Throughout its life, the Rosa 'Dupontii' will repeat the blooming and dormancy cycle annually, while continuing to grow and expand its root system.
PropogationPropogation time
Spring-Early Summer
Rosa 'Dupontii', more commonly known as the Dupont Rose, is best propagated by taking softwood cuttings in the late spring or early summer when the plant's growth is most vigorous. To propagate using softwood cuttings, select a healthy stem that has recently bloomed and cut a piece approximately 6 inches (15 centimeters) long. Make sure the cutting has at least two or three sets of leaves. Remove the leaves from the lower half of the cutting to prevent excess moisture loss and potential rot when planted. Dip the cut end into a rooting hormone to encourage root growth, and then plant it in a mixture of half peat and half perlite or vermiculite to provide a well-draining growing medium. Keep the cutting moist and in bright, indirect light until roots have developed, which usually takes a few weeks. After the cutting has established a robust root system, it can be transplanted into its permanent location.
