About this plant
Solidarity Rhododendron, Solidarity Azalea
Rhododendron 'Solidarity', commonly known as rhododendron, is toxic to humans. All parts of the plant contain substances known as grayanotoxins, which can cause poisoning if ingested. Symptoms of rhododendron poisoning may include vomiting, diarrhea, drooling, weakness, confusion, hypotension (abnormally low blood pressure), and cardiac problems. In severe cases, ingestion could lead to coma or death, although such extreme reactions are rare. It is essential to seek immediate medical attention if someone has consumed any part of a rhododendron plant.
Rhododendron, including the 'Solidarity' variety, is toxic to pets, including dogs, cats, and horses. The plant contains grayanotoxins, which can interfere with normal skeletal muscle, cardiac muscle, and nerve function. If a pet ingests rhododendron, symptoms could include vomiting, diarrhea, hypersalivation, weakness, incoordination, cardiovascular collapse, and potentially coma. In severe cases, it can be fatal. Prompt veterinary care is crucial if a pet has ingested any part of a rhododendron plant.

Azaleas, including the Rhododendron 'Solidarity', prefer consistently moist but well-drained soil. They should be watered deeply once a week, providing about 1 inch of water each time, which is equivalent to approximately 0.6 gallons per square foot of planting area. During hot or dry spells, the frequency may need to increase to twice per week. It's important to avoid overhead watering to prevent fungal diseases and instead water directly at the base of the plant. Overwatering or allowing the soil to remain waterlogged can lead to root rot, so ensure the soil can drain excess water properly.
Azaleas thrive in dappled sunlight or partial shade. The Rhododendron 'Solidarity' should be planted where it can receive morning sunlight and afternoon shade, as direct afternoon sun can scorch the leaves. An ideal spot is under the canopy of tall trees that provide filtered light, mimicking the azalea's natural habitat on the forest floor.
Azaleas, like Rhododendron 'Solidarity', prefer moderate temperatures and can generally withstand minimum temperatures down to 20°F, though there may be variations depending on the specific cultivar. They are most comfortable in temperatures between 50°F and 70°F. Azaleas can suffer heat stress above 80°F, so providing some shade during the hottest part of the day can help manage high temperatures.
Pruning azaleas, like Rhododendron 'Solidarity', is important to maintain shape, encourage bushiness, and remove dead or diseased wood. It's best to prune them immediately after they finish blooming in spring, as pruning later can remove next year's buds. Deadheading, or removing spent flowers, can enhance the appearance and prevent energy going into seed formation.
Azaleas, such as Rhododendron 'Solidarity', require an acidic soil mix with a pH of 4.5 to 6.0. A good soil recipe would be equal parts of peat moss, pine bark, and perlite to ensure proper drainage and aeration. Regular checks to maintain the acidic pH are crucial for the plant’s health.
Azaleas, including Rhododendron 'Solidarity', should be repotted every 2 to 3 years or when they outgrow their pots. Spring is the best time for repotting, right before they enter their active growth phase.
- Humidity & Misting
Keeping Azaleas like Rhododendron 'Solidarity' at a humidity level of around 50-60% is ideal. They benefit from higher humidity but it is not mandatory for their survival.
- Suitable locations
Place Rhododendron 'Solidarity' in bright, indirect light.
Plant Rhododendron 'Solidarity' in partial shade.
- Life cycle
The Rhododendron 'Solidarity' begins its life cycle as a seed, typically requiring stratification to break dormancy before germinating in favorable conditions of moisture and temperature. Upon germination, it develops into a seedling with a root system and cotyledons, before true leaves emerge, allowing it to photosynthesize. As the seedling matures, it grows into a young plant, establishing a more extensive root system and foliage, and eventually starts to form woody stems. The young rhododendron gradually matures into an adult plant capable of flowering; in optimal conditions, it will produce showy blooms annually, typically in the spring. After pollination, flowers develop into seed capsules that, when mature, release seeds to start the next generation. Throughout its life, it goes through cycles of dormancy and active growth, with leaves that may persist across seasons in milder climates, as most rhododendrons are evergreen.
The Rhododendron, commonly referred to as the Azalea, is best propagated through several methods depending on the time of year, but the most popular and effective method is semi-hardwood cuttings. This technique is typically carried out in the late summer after the plant has finished blooming and the new growth has begun to harden. Cuttings should be taken from healthy, disease-free plants, and it's important to choose semi-hardwood stems, which are matured enough but not fully hardened. The cuttings, usually 4 to 6 inches (10 to 15 centimeters) in length, are treated with a rooting hormone to encourage root development and then planted in a mixture of perlite and peat for optimal rooting conditions. They should be kept in a humid environment until roots have established, which can take several weeks. Once rooted, the cuttings can be transferred into individual pots to continue growing before eventual transplanting into the garden.
