Lilacs can bloom in August, although it is not very common for most lilac varieties. However, there is a specific variety called the “Bloomerang” lilac, developed by Proven Winners, that is known for its ability to re-bloom in late summer or early fall, including August or September. This particular lilac variety is a hybrid of Syringa patula and Syringa meyeri, and it has been bred specifically to produce multiple bloom cycles throughout the growing season.
The Bloomerang lilac is a fantastic option for those who want to enjoy lilac blossoms not only in spring but also later in the summer. This variety typically begins blooming in late spring or early summer, like other lilac varieties, but it doesn’t stop there. After the initial bloom period, it takes a short rest before producing a second flush of flowers in late summer or early fall.
These reblooming lilacs are known for their compact and rounded growth habit, reaching a mature height and spread of about 4-6 feet. They are generally hardy and low-maintenance, making them suitable for various garden settings. The Bloomerang lilacs are also highly fragrant, with a sweet and intoxicating scent that fills the air around them.
While the Bloomerang lilac is the most well-known reblooming variety, there are a few other lilac types that may exhibit late-season blooms, albeit less reliably. One such variety is the Dwarf Korean lilac (Syringa meyeri ‘Palibin’), which is a smaller and more compact lilac bush that typically blooms in early to mid-spring. However, in some cases, the Dwarf Korean lilac may surprise you with a second round of blooms in late summer or early fall.
It’s important to note that while some lilacs may have the potential to rebloom in August or later, the occurrence of late-season blooms can vary depending on factors such as climate, growing conditions, and the specific cultivar. So, it’s always a good idea to check the specific characteristics and recommendations for the lilac variety you are interested in.
In my personal experience, I have seen the Bloomerang lilacs in full bloom during August, and it was a delightful surprise to witness such vibrant and fragrant flowers during the late summer months. The reblooming aspect of these lilacs adds a unique charm to the garden, extending the lilac season beyond the traditional spring bloom.
To summarize, while most lilacs bloom primarily in spring, there are specific varieties like the Bloomerang lilac and occasionally the Dwarf Korean lilac that can exhibit late-season blooms, including August or even later. These reblooming lilacs offer an opportunity to enjoy the beauty and fragrance of lilac blossoms throughout the growing season, creating a delightful addition to any garden.
