rhododendron 'Mrs Charles E. Pearson'


The Rhododendron 'Mrs Charles E. Pearson' is a stunning plant known for its impressive floral display. This rhododendron variety boasts large, lush leaves that are dark green in color, providing a perfect backdrop for its flowers. These leaves can have a glossy, leathery texture that complements the overall lush appearance of the plant. The most striking feature of this rhododendron is its flowers. They are showy, with each blossom comprising multiple petals that create a full, rounded shape. The flowers are typically a shade of pink, which can range from soft, pastel hues to more intense, saturated tones. The pink may be uniformly colored or can have variations such as darker or lighter spots, that add depth and interest to the flower clusters. These flowers grow in clusters, known as trusses, which emerge in abundance and can create a spectacular floral display that is visually striking. The trusses are made up of several individual blooms that come together to form a dense, dome-like shape, which is characteristic of many rhododendron varieties. The plant tends to have a bushy and well-branched structure, which allows the floral display to be distributed across the plant, making it appear full and vibrant when in bloom. The contrast between the dark foliage and the bright flowers provides a stunning display that can be a highlight in any garden. Because precise measurements, including any mention of the size of the plant, are to be omitted, we will not be discussing how tall or wide this variety typically grows. However, it is worth noting that rhododendrons, in general, have a natural range of sizes and can fit in a variety of garden settings depending on the species and growing conditions.

  • skullToxicity

    • To humans

      Rhododendron is a highly toxic plant when ingested by humans. All parts of the plant, including leaves, flowers, and nectar, contain grayanotoxins, which can cause poisoning. Symptoms of rhododendron poisoning can include vomiting, diarrhea, drooling, hypotension (low blood pressure), bradycardia (slow heart rate), and cardiac arrhythmias. Severe cases may lead to coma, convulsions, and death if not treated promptly. The severity of symptoms typically depends on the amount ingested.

    • To pets

      Rhododendron is also toxic to pets, including dogs and cats. Similar to humans, the ingestion of any parts of the plant can cause severe problems. Symptoms of rhododendron poisoning in pets include vomiting, diarrhea, hypersalivation, weakness, loss of coordination, and in severe cases, seizures, coma, and potentially death. Immediate veterinary attention is required if a pet ingests any part of a rhododendron.

As needed
  • water dropWater

    Rhododendrons, including 'Mrs Charles E. Pearson', prefer well-drained soil with consistent moisture. Water this plant deeply when the top inch of soil feels dry to the touch, typically once a week, providing about one inch of water each time, which is roughly 0.6 gallons for an average-sized shrub. During periods of high heat or drought, increase watering frequency to prevent stress. Avoid overwatering as Rhododendrons are prone to root rot. In winter, reduce watering since the plant's water needs decrease.

  • sunLight

    The Rhododendron 'Mrs Charles E. Pearson' thrives in dappled shade to partial sunlight. It's best placed in a location where it's protected from harsh afternoon sun, which can scorch the leaves. Morning light with afternoon shade or filtered light beneath tall trees is ideal for this plant's growth and flower production.

  • thermometerTemperature

    Rhododendrons, like 'Mrs Charles E. Pearson', prefer mild conditions and can survive in temperatures as low as 20°F and as high as 80°F, although they thrive best between 60°F and 75°F. They can endure short periods of colder temperatures but require protection from frost to avoid damage.

  • scissorsPruning

    Prune the Rhododendron 'Mrs Charles E. Pearson' to maintain its shape, remove dead or diseased branches, and promote bushier growth. The best time for pruning is immediately after flowering, which is typically late spring to early summer. Prune sparingly as Rhododendrons do not require heavy pruning and can take a few years to recover from aggressive cuts.

    As needed

  • bambooSoil

    The best soil mix for a Rhododendron, also known as azalea, should be well-drained, high in organic matter, and slightly acidic with a pH of 4.5 to 6.0. A mixture of pine bark, peat moss, and perlite in equal parts often works well to provide the necessary aeration and drainage.

  • plantRepotting

    Azaleas typically require repotting every 2 to 3 years, or when they become root-bound. It's best to repot in late winter or early spring just before new growth starts.

  • water dropsHumidity & Misting

    Azaleas thrive in moderate to high humidity levels, ideally between 50-60%. They benefit from regular misting or placement on a pebble tray with water to increase the ambient humidity.

  • circleLife cycle

    The life of Rhododendron 'Mrs. Charles E. Pearson', also known as the Rhododendron, typically starts from a seed or cuttings. After germination or root development, the seedling or cutting grows into a juvenile plant, establishing roots and sprouting the first leaves and stems. As it matures, the Rhododendron enters its vegetative stage, producing a bushy growth of evergreen leaves and increasing in size. The reproductive stage follows, where the plant develops buds that bloom into large, showy flowers, usually in late spring. After pollination, the flowers produce seed capsules for propagation, although Rhododendrons are often propagated vegetatively. Finally, as the plant ages, it may enter a period of decline, manifested by reduced flowering and vigor, until it eventually dies.

      Spring-Early Summer

    • The Rhododendron 'Mrs Charles E. Pearson' is commonly propagated through semi-hardwood cuttings, a method that is often employed during the summer months when the plant has ceased its primary growth phase but the stems are not yet fully hardened. A cutting should ideally be 4 to 6 inches (approximately 10 to 15 centimeters) long and include several leaf nodes. Remove the lower leaves, dip the end in rooting hormone, and then insert the cutting into a mixture of perlite and peat moss. The cutting needs a warm, humid environment to encourage root growth, which can be achieved by covering it with plastic and placing it in indirect light. Regular misting helps maintain humidity, and roots typically develop within several weeks to a few months. Once rooting is evident, the new plant can be transferred to a more permanent pot or outdoor location.
