Japanese Tree Lilacs (Syringa reticulata) are beautiful trees that are known for their large clusters of fragrant white flowers that bloom in June. They are deciduous trees that are native to Japan and eastern Asia, and they are prized for their hardiness and ability to tolerate a wide range of soil conditions. In addition to their attractive flowers, Japanese Tree Lilacs have glossy, dark green leaves and shiny, attractive bark. They are generally easy to care for and are resistant to pests and diseases, making them a popular choice for landscaping. They can grow to be up to 30 feet tall and 25 feet wide at maturity, and they are often used as a specimen tree or as a border tree in landscaped gardens.
