Rhododendron shrubs are evergreen or deciduous, with some growing as wild, but most are cultivated. These flowers are popular with most gardeners and landscapers due to their large and attractive flowers.
Cultivated rhododendron are evergreen plants with large leaves and remarkable flowers that bloom in late spring. Most of these flowers bloom from April to June, and sometimes the flowers last until late summer.
Azaleas are attractive flowering shrubs grown for their flowers. Their flowers are not as large and showy as those of the rhododendrons, but they are as popular.
Azaleas are deciduous, which means they will lose their leaves in the fall while Rhododendrons are evergreen – they keep their leaves during winter with the exceptions of R. mucronulatum and R. dauricum.
Rhododendron macrophyllum is found in the Pacific Northwest region of North America. It derives its names from the pacific, Western and Coast Rhododendron. This plant has pink flowers and is used as the state flower of Washington.
Rhododendron care is minimal, which encourages many gardeners to grow these beauties. The care includes adequate watering, pruning, and deadheading the flowers to encourage abundant blooming.
