How to Make Lilac Syrup – Foraging Edible Flowers

This post may contain affiliate links, view our disclosure policy for details.

I have been learning so much about foraging mushrooms and wild plants the past few years – it’s a whole different world to learn about! So this year my focus was on edible weeds and edible flowers. We spent a weekend harvesting lilac flowers to make our simple lilac syrup recipe below, as well foraging for dandelions to make dandelion honey. Just made sure your sources are pesticide free with no chemicals!

Everything turned out AMAZING! AND the great thing is that you can store your freshly made lilac syrup in a mason jar in the refrigerator or even can it for later! I can hardly wait for next year’s batch of lilac flowers to appear now! The fragrance of lilac flowers is soul capturing!

A few years ago I went on a girl’s getaway to Mackinac Island during their Lilac Festival and the aroma was unforgettable. I’ll never forget the soft purple color lining the streets in bunches!

The downside to this simple recipe of course is that lilac trees only bloom a few weeks out of every year so sadly you can’t make this fresh all year long. You can, however, refrigerate your syrup for longer storage. It is amazing to add to fresh lemonade or iced tea!

Ingredients for Simple Lilac Syrup Recipe:

  • two cups water
  • two cups of sugar
  • one cup of lilac flowers
  • Optional: four blackberries

Instructions to Make Simple Lilac Syrup:

1. Pick fresh lilac flowers and remove any green stems, bugs or debris. I gave my lilac blossoms a quick rinse with cold water. 

2. Combine two cups of water, two cups of sugar, one cup of fresh lilac flowers and three blackberries if desired for color into a medium sized pot. Mix well with a spoon.

3. Bring your pot to a hard boil while mixing the sugar well to dissolve.

4. Turn off the heat and cool completely.

5. Use a fine-mesh strainer to strain your syrup to remove flowers and berries.

It’s that simple! At the bottom of this post you can print out a recipe card to keep with you in the kitchen to make sure you don’t miss any steps in making lilac syrup – but it’s really easy!

 Below are some tips I learned this year while picking lilac flowers for my syrup.

Tips for Foraging Lilac Flowers:

This year was my first year doing something other than sniffing my lilac flowers! They smell AMAZING but last only a few short weeks each year. I tried two different batches of lilac syrup – one batch with brand new fresh lilac flower blooms and one batch with flowers that were well into bloom and ready to die. What a HUGE difference in flavor!

I definitely recommend that you pick the brand new fresh lilac flowers just after they’ve opened for the best flavor! 

  • Pick the newest freshest flowers
  • Remove any green from the flower
  • Process immediately or leave in the refrigerator

The best way to use your lilac flowers for freshness is to make your lilac syrup right away. Although you can leave the lilac flowers in the refrigerator overnight if needed.

Just fill up a large bowl or colander with fresh lilac flowers, then get settled into a chair to process them!
