Common Lilac
Syringa vulgaris
Family Oleaceae
For a hundred and fifty years, common lilac has been the smell of an American May — perfume heavy enough to find with your eyes closed, on eight-to-fifteen-foot shrubs that outlive the houses they're planted beside. Farmsteads vanish; their lilacs keep right on blooming.
Hummingbirds, butterflies, and bees all show up for the party, cut panicles perfume whole rooms, and once established it barely asks for water. It's safe around pets and children and nearly immortal in a sunny corner. Plant one where the kitchen window can supervise it.

What each band means
- Bloom — flowers open — pollinators working, frost on blossoms is the danger.
- Prune — shape it now — cuts heal cleanly and structure is visible.
These are the species' typical months — expect them a few weeks earlier in warm zones and later in cold ones. Watch the plant, not just the calendar.

Cut stems when half the panicle is open; smash stem ends for vase life.
How do you propagate common lilac?
