Oleanders: Beauty and Functionality on Spain's Highways

Oleanders (Nerium oleander - Adelfas) are hardy shrubs that adorn the median strips on many Spanish highways. Their lush blooms come in shades of pink and white and their red color makes them an aesthetic element of the landscape, but their role goes far beyond that.

These plants are selected for their ability to survive in extreme conditions, such as drought and exhaust fumes. Their rapid growth and dense foliage create a visual barrier between traffic lanes, reducing glare from headlights and minimizing the impact of crosswinds on vehicles.

However, it is important to remember that oleanders contain toxic compounds that can be dangerous if ingested, so caution is required when using them in public spaces. Nevertheless, thanks to their low maintenance requirements and high resilience, they are an ideal choice for green belts and roundabouts throughout Spain.

Oleanders combine beauty with functionality on roads, enhancing the landscape while also contributing to road safety.
