Lilacs Flower Facts

Lilacs are related to the Oleaceae family, and they have a genus of at least 20 to 25 flowering species. In addition, there are over 1,000 types of lilac bushes all over the world.

One of the great things about lilacs is that their bushes can survive hundreds of years, regardless of the local weather.

Plant Name and Origin

The genus name of a Lilac flower is Syringa and it’s derived from an Ancient Greek word: syrinx, which means ‘’pipe’’ and ‘’tube’’ (1).

The first time that this plant was officially described was in 1753 when Carl Linnaeus (a Swedish botanist and zoologist) wrote a description about it and published it in Species Plantarum (2).

However, the English word for ‘’lilac’’ comes from the French word ‘’lilac’’, and, in turn, this French word comes from the Arabic word which is ‘’lilak’’. And, ultimately, this Arabic word is believed to come from a Persian word which is ‘’nilak’’ and it means ‘’bluish’’.

These beautiful flowers have originated in Asia and Eastern Europe, hence why the name is derived from a Persian word.

Syringa vulgaris is the most common lilac and it is also the oldest lilac to be cultivated. It was brought to America in the 1700s by the earliest settlers that were coming from Europe, and people were amazing and how easy it was to cultivate them and how beautiful they smelt.

Legend has it that two of the U.S Founding Fathers, George Washington, and Thomas Jefferson, used to love lilacs. In fact, they even grew them in their gardens (3).

General Description and Characteristics of Lilacs Flowers

Even though the most common type of lilac is the syringa vulgaris, many other types of lilacs that exist nowadays.

In addition, some lilacs hybrids have been introduced by several people, such as Monsieur Victor Lemoine of Nancy, France. He started breeding this flower in the 1800s, and he and his nursery became famous because they developed the well-known French lilacs that have extremely fragrant double blossoms.

Other individuals also presented other types of lilacs, for example, Isabella Preston introduced later-blooming varieties that were of different colors from the usual lilac flowers.

Lilacs Flower Description

How To Grow Lilacs

growing lilac

Growing lilacs is not as difficult as you may think. You will first need to choose a site to grow your lilacs. This site must have full sun but it also needs to be a moist and well-drained soil. 

Below are some specific instructions and guidelines to follow, for whenever you choose to grow your own lilacs. 

Location is Everything

The area you choose to grow your lilacs must be fertile, well-drained, and, if possible, neutral to alkaline soil.

Also, remember that lilacs need to be exposed to sunlight, so try to plant your lilacs in an open area (6)

Water your lilacs

Water is important for any plant, but more so when you are trying to grow some lilacs. However, you will also need a  good drainage system if you are planting the flowers in your garden. 

With a drainage system, you will only use the necessary amount of water, and all the extra water can simply go away and be used for something else. 

And even though lilacs love water, you also need to make sure you don’t overwater them.

The Best Soil for your Lilacs

If you can, run a simple test and see what the results tell you about your soil. The optimal pH level should be near 7.0. But don’t stress about it either, because there are many ways to help your soil get in the best condition. 

If you see your soil is poor in nutrients, then try to enrich it by adding some compost to it. Lilacs love it when the soil they are growing up into is rich and full of nutrients. And, if on the other hand, you have problems with your soil as it becomes acidic, try adding garden lime to it and you will soon recover the soil alkaline levels.

When choosing lilac companion plants, you need to make sure those companions have similar growing conditions, especially soil requirements.

Plant your Lilacs 

Once you are ready to plant lilacs, make sure you make a big hole so your plant has enough space to grow. You then place your plant and immediately start filling the rest of the hole with soil. 

Make sure you water it as well, especially during the day you plant it. If you live in a place with dry weather, then you should also water it constantly. 

If you are lucky enough to have several lilac plants then try to place them between 5 and 15 feet apart from each other. It will all depend on the variety of plants you have, but make sure you leave enough room for them to fully grow and blossom.

Care and Maintenance

Pay close attention to your lilacs but try not to stress about it! Each spring you can put compost under your plant and, at the same time, you can place a 2-inch layer of mulch. This will help you to retain moisture and to control weeds that may damage your lilacs.

If your summers are very hot then you must water your lilacs. 

Even though lilac trees require maintenance, it can be argued that this is a simple step to make sure your plants will grow properly.

Lilacs are well-known for enduring droughts and severe weather, and they actually survive. 

After three years, you will be able to see your lilacs producing flowers. 


Deadheading lilacs should be done as soon as the flowers fade. It should also be done annually in order to maintain the health of the lilacs. 

Just make sure you cut the old flower and its cluster at its base, this way you are making space for new shoots to grow over the following summer.

Pests and Diseases

Nature is very wise, and this is why slugs and snails love to attack lilacs. Well, in all honesty, slugs love damaging all gardens, and they are considered pests. 

Make sure your lilacs are not having visits by these two pests, because if they do, they are more likely to grow fewer flowers and leaves, thus they will not reach their full potential. 

During the summer, it is very common to see powdery white mildew on your lilac plants. And even though it may seem like a really bad thing to happen, in reality, it doesn’t harm your lilacs. 

If you would like to apply fertilizer to your lilac plant, then why don’t you put a layer of compost under the plant? You must be careful not to over-fertilize your lilacs because if you do so, they will not bloom. 

Lilacs also like manure, so if you happen to have any, put some on their roots, they will be grateful for it.  

Pruning Lilacs

When your plant is small, and if it has flower heads then try to cut them within the first month of their first appearance. 

Once you do this, you will soon realize that your plant will focus on preparing itself to produce more flower buds, which, in turn, will also help the overall well-being of the lilac plant. 

If you think your plant is becoming too tall, then you can also cut some branches. If, on the other hand, your branches are short, you can cut 10 to 15 inches of the main stems from the soil, and this will help your branches grow. 

Try to follow this pruning for at least the first three years of your lilacs plants’ life.
