White-flowered shrubs are a popular choice for landscaping due to their attractive blooms and hardiness. Two common examples of white-flowered shrubs are spireas and oleanders. Spireas are deciduous shrubs with small white flowers that bloom in the spring and summer. Oleanders are evergreen shrubs with large, fragrant white flowers that bloom throughout the year. Both shrubs are relatively easy to care for and can be used to create a beautiful landscape.
