Lilacs’ cultural significance is documented in Greek Mythology. Pan, the god of the fields and forests, fell in love with the nymph Syringa or Styrix. His love was not reciprocated – Syringa was tired of being chased by Pan, so she turned herself into a lilac shrub. Pan couldn’t find her, but he did discover the lilac shrub and constructed his famous instrument — the pan flute — from the lilac’s hollow stems.

The Ancient Celts considered lilacs’ scent to be magically intoxicating. In Russia, a sprig of lilac held over a newborn is said to impart wisdom.

To the Victorians, lilacs symbolized lost love. Women sometimes wore lilacs during periods of mourning.

How to Care for Fresh Cut Lilac Flowers

To keep cut lilacs fresh, use a sharp knife to cut stems above a bud, leaf, or stem at the desired length. Fill a vase with warm tap or distilled water, and add a floral preservative if desired.

Keeping the stems submerged so as not to expose them to the air, cut off any leaves or branching stems that will remain underwater. Next, use the knife to make an “x” at the end of each woody branch. Cut from 1 to 4 inches deep, so the branch splits slightly.

Transfer the stems to the prepared vase. Display the flowers out of direct sunlight and away from drafts. If possible, place them in the refrigerator at night. When the vase water looks cloudy, cut off half an inch of stem and replace it with fresh water.
