Common White Lilac
The Classic Pure-White Heirloom Lilac
Common White Lilac (Syringa vulgaris 'Alba') is the timeless white form of the beloved old-fashioned lilac — a tall, vigorous shrub smothered in clusters of pure-white, intensely fragrant flowers each spring. The crisp white blooms glow at dusk and perfume the whole garden, drawing butterflies. Exceptionally tough and deer-resistant, it's a heritage choice for fragrant hedges, screens, and specimens in Edina, Woodbury, and Maple Grove.

Landscape Uses in Minnesota
Fragrant hedges and screens: Its vigorous, upright form makes a classic flowering privacy screen or property-line hedge. Space 6–8 feet apart.
Pollinator and cut-flower gardens: Butterflies flock to it, and the white blooms are stunning in a vase and glow at twilight. Pair with peonies and catmint.
Best Time to Plant in Minnesota
Plant in spring (late April–May) or early fall (late August–mid September) in full sun with good drainage.
How to Plant Common White Lilac
Dig a hole twice the root ball width at the same depth, mixing in compost. Set the crown level, backfill, water well, and mulch 2–3 inches deep, keeping mulch off the stems. Space 6–8 feet apart.
Watering Common White Lilac
First year: Water deeply every 2–3 days at first, then weekly. Stop 2–3 weeks before the ground freezes.
After year one: Quite drought-tolerant — water during extended dry spells. Avoid soggy soil.
Q: Will it survive a Minnesota winter?
Absolutely — the common lilac is one of the toughest, longest-lived shrubs in cold climates and needs winter chill to bloom well.
Q: How do I keep it blooming?
Full sun and pruning right after flowering (it blooms on old wood). Remove old canes occasionally to renew it; avoid late-summer pruning.
Q: Does it sucker?
It can spread by suckers to form a thicket — great for hedges, but remove suckers for a single specimen.
Q: Is it deer-resistant?
Yes — deer rarely browse lilacs.

Common White Lilac Season-by-Season in Minnesota
- Spring: The headline act — clusters of pure-white, intensely fragrant blooms in mid-to-late spring that glow at dusk and perfume the whole yard; butterflies work the flowers.
- Summer: Dense, heart-shaped blue-green foliage forms a solid privacy screen.
- Fall: Foliage stays green late, then drops without much color change — lilacs spend their show in spring.
- Winter: Stout, multi-stemmed canes shrug off -40°F; the thicket habit still breaks wind and frames the snow line.

Is Common White Lilac Right for Your Yard?
Choose it if you have 6+ hours of sun, well-drained soil, and room for an 8–12 ft shrub — it rewards you with decades of fragrant white bloom, shrugs off deer, and barely needs watering once established. It's not a fit for shady yards or tight foundation beds: bloom drops off sharply below 6 hours of sun, and its suckering, full-size habit overwhelms small spaces.
