Make a big statement each spring with a profuse display of red buds and sweet-scented magenta-purple flower panical clusters that reach nearly a foot-long! Congo Lilac (Syringa vulgaris 'Congo') is a beloved French Hybrid Lilac, well-known for its exceptional hardiness and vigor.

Well-branched Lilac shrubs work hard in any landscape…and heirloom Congo Lilac is no exception. Cloaked for summer in heart-shaped green foliage, it becomes an impressive privacy screen that couldn't be easier to care for!

Planting and Application:

With bold color and heavy bloom production, Congo makes a worthy addition to just about any garden. Plan carefully and utilize several sides of the shrub to maximize the investment in space

  • Plant a big, blowsy hedge along your property line. You'll gift your entire neighborhood with their delightful fragrance.
  • Set up your outdoor entertainment area to take advantage of the other side of your privacy hedge. Lilac shrubs make near-perfect privacy…you'll love their shelter but never feel "penned in".
  • Carve out a private reading nook for yourself with a hammock or chaise on the far end. What wonderful memories you'll create each spring!
  • Choose Congo Lilac to use as an anchor at the corner of your home's front yard foundation planting. This is a light-hearted choice that offers plenty of interest and lives nearly forever with proper care!
  • Use a showy row of these durable Lilacs as a large-scale backdrop for Butterfly and Pollinator Gardens. Their long-lasting spring display is a favorite nectar resource…sneak a few blooms for cut flower arrangements indoors!

#ProPlantTips for Care: 

Plant in full sun with at least six hours of sunlight a day. They need well-drained soil, but aren't particularly fussy about soil type.

  • Add the symbiotic Nature Hills Root Booster in the planting hole of new shrubs for life-long support. Get more expert planting tips from the NatureHills.com Horticulture team.
  • Start your Lilac off right with supplemental water given on a regular basis. Thereafter, provide water when the weather gets dry and mulch over the root zone, pulling it away from directly touching the stems.
  • Prune to shape once the flowering is done for the season. Congo Lilac blooms on old wood; so don't wait too long to prune or you'll risk cutting off next year's flower buds.
