Rhododendron ponticum aka Rhododendron
Taxonomy
Rhododendron ponticum, also known as common rhododendron or pontic rhododendron, is a stunning and hardy evergreen shrub native to the Iberian Peninsula in southwest Europe and the Caucasus region in northern West Asia. It belongs to the Ericaceae family and is closely related to popular plants like azaleas, blueberries, and cranberries. This densely branched shrub features tough, leathery, dark green oval leaves and produces terminal trusses of 10 to 15 purple, funnel-shaped flowers in the spring. Despite its toxicity to livestock due to the presence of grayanotoxins in its nectar, the Pontic Rhododendron remains a favored ornamental plant for its showy pink or purple blooms. With proper care, this flowering plant can thrive in various climates and provide years of beauty and pleasure. Its glossy, dark green oblong leaves and trumpet-shaped clustered flowers make it easily identifiable. Additionally, it is often used as a rootstock, demonstrating its resilience even when the grafted variety has perished.

Difficulty
Rhododendron requires a bit more attention and knowledge to thrive, making it a suitable plant for those with some gardening experience.
Water
Rhododendron should be watered regularly, allowing the soil to dry out between waterings.
Soil
Rhododendron loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.
Lighting
To ensure optimal growth, the Rhododendron prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.
Toxicity
Ploi's records do not contain confirmed information on the toxicity of this particular plant. In the event of accidental ingestion of plant material with questionable toxicity by you, a family member, or a pet, it is always a good idea to consult a healthcare professional.
Humidity
The Rhododendron is not in need of supplementary humidity. Most water is taken in by plants through their roots, thus soil watering is the most efficient way to provide humidity to your plants.
Fertilizer
The growth of Rhododendron is not rapid and it doesn't necessitate any extra fertilization. By replacing its potting soil once a year, it should receive ample nutrition. It is important to note that plants obtain their energy from the sun's rays, not from fertilizers.
Region of origin
Rhododendron’s native range is Asia and North America.
