Lilac trees are fragrant and beautiful as they produce blooms during the springtime months. Lilac trees are hardy perennials that grow in USDA zones 3 to 7. Even though they are easy to grow, lilac trees do require light maintenance to keep the plant healthy and under control.
Lilac trees are natives of Europe and were introduced to the United States in the mid 1700s. Since lilac trees can live for hundreds of years, it is likely that trees planted back then may still be alive today.
Proper care for lilac trees is significant to the health and well-being of the young tree. Trees must be planted in a sunny location in well-drained soil. Lilac trees will suffer from root rot if they are in soggy soil. The dead branches and extra long stems should be pruned each year during the summer months, following the blooming period.
Lilac trees can grow to be 20 to 30 feet tall and display white or purple cone-shaped flowers, which are extremely fragrant. The lilac tree's bark is smooth and grayish-brown in color. The leaves of the lilac tree are dark green and shed during the autumn months without changing color.
There are many species of lilac trees that grown in gardens around the United States, but two are the most commonly recognized. The common lilac tree displays purple flowers, and the Japanese lilac tree produces flowers that are white.
It takes four to seven years for a lilac tree to grow to full size and produce a maximum amount of flowers. Lilac trees can live for hundreds of years, but if one is extremely cut back it may take at least two years for it to regain a maximum amount of blooms.
