Daurian Rhododendron Rhododendron dauricum 'Mid-winter'
ABOUT
The 'Mid-winter' rhododendron is a striking plant known for its beautiful blossoms that brighten up gardens even during the chillier months. Its leaves are leathery with a dark green hue, providing a rich backdrop to the splashes of color from its flowers. These blossoms can range from light pink to a rosy purple, often with a lighter center and darker edges. What's particularly distinctive about the rhododendron's blooms is their shape – they have a trumpet-like form, which gives the plant a spectacular display when they flourish in clusters. The buds may have a slightly reddish tinge before they fully open, adding to the plant’s aesthetic appeal throughout its blooming period. It's also noteworthy that the 'Mid-winter' rhododendron maintains a somewhat rounded shape in its overall form, contributing to the plant's lush and full appearance.

ToxicityTo humans
Rhododendron, including the 'Mid-winter' variety, contains grayanotoxins, which are toxic to humans if ingested. Symptoms of rhododendron poisoning can range from mild to severe and include nausea, vomiting, drooling, diarrhea, lethargy, weakness, abdominal pain, difficulty breathing, and a decrease in blood pressure. More severe cases can lead to coma, convulsions, and even death. Eating any part of the rhododendron plant can result in poisoning, so it should not be ingested under any circumstances.
To pets
Rhododendron is poisonous to pets, such as dogs and cats. The toxicity is due to the presence of grayanotoxins in the plant. If pets ingest any part of a rhododendron, they may present with symptoms like vomiting, diarrhea, hypersalivation, weakness, coma, hypotension, central nervous system depression, cardiovascular collapse, and potentially death. Immediate veterinary care should be sought if a pet consumes rhododendron.

WaterThe Siberian rhododendron should be watered thoroughly, so the root zone becomes moist, but avoid waterlogging as this can lead to root rot. During the growing season in spring and summer, water the plant with about one inch of water per week, adjusting for rainfall. In hot or windy weather, you may need to water twice a week. During fall and milder winter days, reduce watering but don't let the soil become completely dry. Consistent moisture is key, so checking the top couple of inches of soil for dryness can help gauge when to water.
LightSiberian rhododendrons thrive in locations where they receive partial shade to filtered sunlight. They perform best when protected from the harsh afternoon sun, so planting them in a spot that receives morning light and afternoon shade is ideal. These conditions prevent leaf scorch while providing enough light for healthy growth and flowering.
TemperatureSiberian rhododendron prefers moderate temperatures and can typically survive in minimum temperatures down to about -20°F, and maximum temperatures around 80°F. The ideal temperature range for this plant is between 50°F and 70°F. Extreme temperature fluctuations can stress the plant, so it's best placed in an area with some environmental stability.
PruningPrune Siberian rhododendrons to shape the plant, remove dead flowers (deadheading), and encourage bushier growth. It is best to prune immediately after flowering in the spring to avoid cutting off next year's buds. Light pruning can be done yearly, while more extensive shaping should be done less frequently, as rhododendrons are typically slow growing.
CleaningAs needed
SoilThe best soil mix for Siberian Rhododendron should be well-draining, rich in organic matter, and slightly acidic, with a pH between 4.5 and 6.0. A mixture of 50% pine bark, 30% peat moss, and 20% perlite or coarse sand is ideal to provide the needed drainage and acidity.
RepottingSiberian Rhododendrons should typically be repotted every 2 to 3 years. It's best to repot in early spring before new growth starts or immediately after the blooming period.
Humidity & MistingSiberian Rhododendrons prefer moderate to high humidity levels, ideally between 40% and 60%. They thrive in moist air but should be protected from excessively damp conditions that can promote fungal diseases.

Life cycleThe Rhododendron dauricum 'Mid-winter', commonly known as the Dahurian rhododendron, begins its life cycle with seed germination, which occurs under cool, moist conditions in the spring. After sprouting, it enters a juvenile growth stage where the seedling develops into a young plant with characteristic leaves and an establishing root system. This is followed by a maturation phase, where the plant grows larger, develops woody stems, and reaches reproductive maturity. The Dahurian rhododendron then enters its flowering stage, typically in mid-winter to early spring, during which it produces vibrant flowers that attract pollinators. After pollination, the flowers form seed capsules, which eventually disperse seeds, completing the reproductive cycle. The plant may then enter a period of dormancy, particularly in colder climates, where it conserves energy until the next growing season.
PropogationPropogation time
Spring
Rhododendron dauricum 'Mid-winter', commonly known as Midwinter Rhododendron, can be effectively propagated through semi-hardwood cuttings. The best time for this method is typically during the late summer. To propagate by cuttings, a healthy, non-flowering shoot is selected and a cutting about 4 to 6 inches (approximately 10 to 15 centimeters) in length is made. The lower leaves are removed, and the cut end can be treated with a rooting hormone to encourage root development. The cutting is then inserted into a well-draining potting mix or propagating medium, ensuring the leaf nodes where the leaves were removed are buried, as these spots are where roots are most likely to form. The container with the cutting should be kept moist and placed in indirect light until roots have developed, after which it can be potted up or planted out as desired.
