rhododendron 'Norma'


The Rhododendron 'Norma' is a visually striking plant known for its lush, evergreen foliage and vibrant blossoms. Its leaves are a deep, glossy green, providing a rich backdrop for the flowers. The blooms, appearing usually in late spring, are its most captivating feature, with a bold, rosy-pink hue that can range from soft to more intense shades. These flowers are often bell-shaped, with a slight ruffle at the edges, and gather in large, showy clusters known as trusses, which can create a spectacular display contrasted against the dark green leaves. Each individual flower is composed of several petals fused at the base, typical of Rhododendrons, giving the blooms a full, rounded appearance. The plant's overall lushness and the abundant, colorful blossoms make it a favorite for adding a splash of brightness to garden spaces.

  • water dropWater

    Rhododendrons, including 'Norma', prefer consistently moist soil, so they should be watered thoroughly whenever the top inch of soil feels dry to the touch. Typically, this might mean watering once a week, but frequency can vary depending on climate, weather conditions, and soil type. It is important to avoid overwatering to prevent root rot, ensuring the plant is in well-draining soil. In terms of amount, during dry periods, provide about 1 gallon of water per foot of plant height each week. Adjust this amount during rainy seasons or in cooler climates where the soil retains moisture longer.

  • sunLight

    Rhododendrons like 'Norma' thrive best in dappled shade. They often succeed under the canopy of larger trees where they receive filtered sunlight. Direct, harsh afternoon sunlight can damage the leaves, while too much shade can result in poor blooming. An eastern or northern exposure is often ideal, providing the necessary bright but indirect light.

  • thermometerTemperature

    The ideal temperature for the Rhododendron 'Norma' is a range between 50°F and 70°F. These plants can survive minimum temperatures down to about 0°F but can be damaged by frost. Protection from cold winds and proper mulching can help them survive the colder end of the temperature range.

  • scissorsPruning

    Rhododendrons like 'Norma' should be pruned to maintain shape, encourage bushier growth, and remove dead or diseased branches. The best time to prune is soon after the blooming period has ended, which is typically in late spring or early summer. Deadheading, or removing spent flower clusters, can also promote better blooms the following year. Make clean cuts at a 45-degree angle just above a healthy set of leaves.

  • circleLife cycle

    The Rhododendron 'Norma', commonly known as a type of Azalea, begins its life cycle as a seed, which after germination, grows into a seedling. As the seedling matures, it develops a root system and foliage, entering the vegetative stage. Over time, the vegetative plant grows larger and eventually starts to produce buds, signaling the onset of the reproductive stage. The buds bloom into characteristic flowers, which after pollination, develop into seed capsules containing numerous seeds. Once the seeds are dispersed, the cycle can begin again with new seedlings. Throughout its life, which can span several decades with the right care, the Rhododendron 'Norma' may undergo periods of dormancy, typically in colder months, before resuming growth in the spring.

    • Propogation time

      Late winter to spring

    • Rhododendron 'Norma', commonly known as a variety of Rhododendron, is most effectively propagated by semi-hardwood cuttings. The optimal time for taking cuttings is during the late summer months, typically from July to September. To propagate by this method one should select healthy, semi-hardwood stems from the current year's growth. These cuttings should be about 4 to 6 inches (about 10 to 15 centimeters) long, with the lower leaves removed. The cut end of the stem should be dipped into a rooting hormone to encourage root development and then placed into a potting mixture that is well-draining and kept consistently moist but not waterlogged. The pot should be placed in a warm, shaded area, and covered with a plastic bag or put into a greenhouse to maintain high humidity around the cuttings. Roots typically develop within several weeks, after which the new Rhododendron plants can gradually acclimate to outside conditions before being planted in their final location.
