Purple lilacs, also known as common lilacs (Syringa vulgaris), are beautiful and popular flowering shrubs that can add a touch of elegance to any garden or landscape. These lovely plants can reach a height of 12 to 15 feet and have a width of 10 to 12 feet when fully mature. However, it is important to note that this is the average size range, and individual plants may vary slightly.
If you are looking for a smaller variety of lilacs, there are also dwarf cultivars available. These compact versions of the common lilac typically reach a mature height of 4 to 6 feet and have a width of 3 to 7 feet. These dwarf lilacs are great options for smaller gardens or where space is limited. They still retain the beautiful purple blooms and fragrance of their larger counterparts, but in a more manageable size.
In addition to the common lilac, there is another type of lilac called the Japanese tree lilac (Syringa reticulata). This variety can grow taller than the common lilac and can reach heights of 25 to 30 feet. The Japanese tree lilac has a more upright and narrow growth habit, which gives it a tree-like appearance. It produces large clusters of creamy-white flowers in late spring or early summer, adding a touch of elegance to any landscape.
When considering planting lilacs, it is important to take into account their eventual size and growth habit. Proper spacing should be provided to allow for the mature size of the plant and to prevent overcrowding. This will ensure that the lilacs have enough room to grow and flourish, and will also make maintenance and pruning easier.
In my personal experience, I have planted both common lilacs and dwarf lilacs in my garden. The common lilacs have reached their expected height and width, creating a beautiful and fragrant focal point in my yard. The dwarf lilacs, on the other hand, have provided a more compact and manageable option, fitting perfectly in smaller areas and containers.
To summarize, purple lilacs, specifically the common lilac (Syringa vulgaris), typically grow to a height of 12 to 15 feet and have a width of 10 to 12 feet. There are also dwarf varieties available, which mature at a height of 4 to 6 feet and have a width of 3 to 7 feet. The Japanese tree lilac (Syringa reticulata) can grow taller, reaching heights of 25 to 30 feet. Proper spacing should be considered when planting lilacs to accommodate their mature size and ensure optimal growth and beauty.
