My life as a crunchy, frugal Oregonian. I’m walking past a lovely lilac shrub near my house and considering the ways to utilize those fragrant blossoms. Soon the blooms will be gone, so now is the perfect time to harvest them for more than bouquets.

Not only is the lilac bush beautiful and colorful, but the aroma of the flowers tastes good enough to eat

Fun fact: the flowers from the variety of lilacs Syringa vulgaris are safe to consume – so, simple syrup it is!

A simple process of steeping the blossoms in sugar water produces a fragrant lilac syrup that you can use in a number of delicious ways.

Note: While the common lilac has edible purple flowers, the Persian lilac is commonplace in landscaping and toxic if ingested. Determine the species before consuming the plant.

FAQs

How do I store lilac syrup?

Store in an airtight jar in the refrigerator for up to two weeks. You can also freeze it in an ice cube tray to use later.

Why is my syrup bitter?

Lilac syrup might become bitter if the blossoms are boiled rapidly rather than gently simmered and slowly infused.

Do lilac blossoms have any health benefits?

Aside from their lovely aroma, lilacs are known for their calming properties as well as immune system support with vitamins A and C.

How are lilacs different from lavender?

While often confused for their similar look and color, lilacs typically have a stronger floral fragrance and lavender is more toned down, herbal, and calming. Lilacs are shrubs that present a warmer, pink tone, while lavender is a perennial herb with a cooler, purple tone.
