Can Lilacs Grow In Florida?

Lilacs are one of the most popular trees that you can find in almost every garden in the US. In general, lilacs are considered cold-weather perennials native to Asia and Eastern Europe. However, there are issues with lilacs not being able to grow in all regions, especially the ones with a subtropical climate. Like many other people who live in Florida, you may wonder: can lilacs grow in Florida?

Unfortunately, lilacs aren’t the best flowers that you can grow in Florida, and for a good reason. Florida has a warm climate with mild winters. And that makes lilacs challenging to grow in that region.

Syringa vulgaris, or what is known as the common lilac, is a popular plant that can grow up to 12 feet when provided the right atmosphere. However, Florida’s hot and humid climate is conducive to growing lilacs. Besides, the plants won’t survive in the southern and central parts of the State.

Lilacs need a period of cold-induced dormancy so that they can produce new blooms. As a result, these ornamental plants don’t grow well in places that have mild winters. During the cold weather, the lilac buds find the right temperature to mature and bloom for the upcoming spring.

Apart from the weather, the kind of zones plays a significant role in determining whether the plant can grow in Florida. For example, some lilac variants thrive and bloom in hardiness zones 3 to 9. The plant reaches a height up to 8 – 12 feet and has a width of around 6 to 10 feet.

Hence, it can be concluded that lilacs are hard to grow in Florida, and even if you grow them anyhow, they will not produce the result as you see in other states. However, cultivars can bloom a few varieties in lower South Florida to some extent.

Local climate matters a lot when it comes to attempting a blooming and healthy lilac bush. It means that zone restrictions will favor whether a specific plant will bloom in areas denoted by the winter chill.

However, the exact range will depend on factors such as the variety and species of the plant. Furthermore, only a handful of lilac variants have been successfully bred well in warm climates with zone 8. Sadly, a few will thrive in the mild winter climatic condition of zone 9. Still, cultivars are warned to take extra care to have a good show of flowers in spring.
