I have a serious love affair with flowers. Unfortunately, my allergies did not get the memo on my infatuation and keeps many fragrant florals just out of reach. So goodbye jasmine, day lilies, and other perfumed beauties.
But there are many other gorgeous flower options out there for me to enjoy. I frequently shop at my local Trader Joe’s to pick up a bouquet or two of chamomiles, peonies, hydrangeas and this week: lilacs!
Why I love this recipe and lilacs
I love gardening, although my green thumb is still a work in progress. I adore flowers, but they don’t all like me. Lilacs are gorgeous and mildly fragrant. But most importantly, they don’t aggravate my allergies!
They come in a variety shades of pinks and purples, and of course the popular color of lilac. Some varieties only bloom for 3 weeks in the spring, while others bloom throughout the year.
Did you know that lilacs belong to the olive family, oleaceae? No wonder I love them! Lilac varieties can grow to be a large tree or in a bush.
Lilacs thrive in cold weather climates, so I’m dying here in Southern California as I am hunting for a warm weather loving lilac. So every time I find lilacs at Trader Joe’s, I have to scoop them up.
There are many varieties of flowers that are edible. My favorite edible flower is of course, the rose. But that’s probably because I’m Persian and we use rosewater and rose petals in many different ways.
Lilacs are also edible. Just be sure that the lilacs you are using are pesticide free. You can use lilacs in simple culinary ways like infusing sugar, alcohol and simple syrups. Lilacs aren’t just for lotions and soaps!
You can bake with lilacs and mix cocktails or sip some lilac lemonade. Garnish a lemon cake with lilacs, bake them into scones, or even add them in some whipped cream. The culinary uses for lilacs are limitless.
Another fabulous way to use up May lilacs is to make a simple syrup. Simple syrups are a great way to sweeten a cocktail or mocktail, and they are easy to mix up.
When making this syrup you want just the blossoms, so remove any leaves or stems before infusing. You also want to gently rinse out the lilacs using a fine mesh strainer to remove any dirt and insects.

Simple syrups are made with equal parts sugar and water. Yup, there’s a reason why it’s called “simple”.
- Water and Granulated sugar: No fancy sugars needed. Just your basic granulated sugar.
- Lilac blossoms: You are fresh and aromatic lilacs that are pesticide free.
- Blueberries: Lilac syrup by itself is kinda brown in color. I add a few blueberries to give it a pretty purple color.
Tools to Use
Step-by-step directions
1. Remove stems and leaves from lilac blossoms, otherwise they can make your syrup bitter. Gently rinse blossoms in a fine mesh strainer and reserve.
2. Add water and sugar in a small pot, whisking together until sugar is dissolved. Bring to boil then add lilac blossoms and blueberries. Simmer for 20 minutes.
3. Pour mixture through a fine mesh strainer to remove all the solids. Allow syrup to cool to room temperature than seal in a jar or bottle. Syrup will keep in the refrigerator like this for up to one month.

Thanks for sharing! Does it keep long?
Hi Vanessa,
In the fridge it can last for up to 6-months. If it turns cloudy beforehand, then it has gone bad.
Laura
This looks so good! What a great craft to make in the spring!
Hi Suzanne-
It’s a great way to add floral tones to your recipes.
Laura
I did this but it won’t thicken. It’s still like water and I followed instructions to a T. How can I fix this?
Simple syrup is always equal parts water and sugar. If it is not thickening up, simmer it longer and the water will evaporate and reduce then your syrup will form.
Laura
I substituted 1 cup of Monkfruit sweetener for the suagr. It turned out GREAT! Thank you for sharing this unique idea/recipe.
Hi Jen-
I love that you used an alternative sweetener! Thanks for sharing.
Laura
ooh, i can’t wait to try this! i live in northern new england, and right now, the lilacs are going crazy. my uncle has a lilac bush on his property that was there since he was a small child; it was so large that, even in the 1960s and 1970s, he and my mother were able to actually climb in it like a tree! i’ll have to pop up there later today and steal some blooms to make this syrup — i imagine it would be really tasty with gin in a cocktail.
I am so jealous of you! I wish lilacs grew well here in San Diego, but alas, it is too warm. Your uncle’s lilac bush-tree sounds like a dream. I hope you enjoy the syrup. Yes, it is delicious in cocktails!
Laura
Laura I just wanted to wish you a happy mother’s day. From your favorite front desk agent in Oceanside. I’m retired now. I love your spices still many many years later .I buy them all the time.. big hug my friend
Hi Susan-
You are so sweet! Thank you! You made my day!
xoxo
Laura
Great tip about adding the blueberries for colour thank you!
You are welcome! Otherwise, well, it looks kinda blah – lol!
Laura
Thanks for sharing! Is it better if they are from the store or from.a local bush?
Hi Vanessa-
I made these with lilacs I bought from Trader Joes, since I can’t grow there here in San Diego. As long as they are fragrant, you can use store bought lilacs.
Laura
This looks so good! What a fun gift to make! I’ve always wondered if that fragrance could be bottled up!
Suzanne,
Pacifica Beauty is an affordable, clean company that sells a french lilac perfume that is divine! My mother wears it almost exclusively!
Can I freeze the lilac blossoms so I could give as gift for Christmas??
A simple freezer will not preserve flower blooms. They have to be freeze dried. You can freeze simple syrup for up to one year. So I suggest making the syrup and then freezing it in a freezer safe container. When you are ready to gift them, thaw the syrup and divide into bottles. You can also dry flower blossoms. They won’t be as fragrant as the fresh flowers, though. Hope that helps!
Laura, I made your recipe and it is wonderful. I want to print your sweet tags but don’t see how to download a printable version. Can you help direct me? Thank you
Hi Megan-
Sorry about that! The link must have dropped off. I put it back in the post and the label is right here:
So glad you liked the syrup!
