What are the disadvantages of rhododendrons?
If allowed to spread, a mature Rhododendron ponticum canopy will displace all ground flora, destroying the rich biodiversity of our natural habitats. Under the dark canopy, the heavy leaf litter acidifies and degrades the soil. A single bush can disperse a million seeds into the wider landscape. It is vital that the three invasive Rhododendron species be prevented from spreading further into our natural environments. Therefore, careful removal and responsible disposal are important when handling this common garden ornamental. All three produce large quantities of viable seed.Rhododendron is a genus of 1,024 species of woody plants in the heath family. It is the national flower of Nepal. Most species have brightly coloured flowers.If the dead flowers aren’t removed, then the plant uses energy to create seeds which takes energy away from the plant and means that it has less to use on flowering in the following season. As a result, your rhododendron will use this extra energy to grow more branches and produce more flowers next year.
Why does Rhododendron mean danger?
The rhododendron plant contains toxins, which if ingested, are harmful to humans and animals which can be a possible reason behind the flower symbolizing caution and danger. Mad honey’ is the toxic honey produced by bees feeding on nectar of Rhododendron ponticum in its native northern Turkey.In addition to their damaging effects on habitats no native insect can survive nibbling rhody leaves, sheep and horses can die from eating them, and even humans have been harmed. There are records, dating back to 400 BC, of honey made from rhododendron nectar adversely affecting people who eat it.
Are mountain laurel and rhododendron the same?

Rhododendron has a longer, darker green, less glossy, elliptical-shaped leaf.

Mountain laurels are ‘understory’ shrubs What this means for planting is that they do well in lots of different situations, whether near a building or underneath an existing tree.This family includes rhododendrons, azaleas, blueberries, and cranberries, all of which are woody shrubs that thrive in moist, well-drained acidic soil. Mountain laurel will grow in USDA Zones 5 to 9 in deep shade to full sun, but it does best in moderate to partial shade.
