    DESCRIPTION

    Bold, dramatic, and unforgettably fragrant — the Congo Lilac makes a powerful statement in the spring garden. This classic French hybrid lilac produces large, commanding clusters of single flowers in a deep, wine-red purple. As the blooms mature, they soften to a rich lilac-magenta, creating a beautiful two-tone effect within each flower cluster that adds depth and visual intrigue to the display.

    Congo is a vigorous, upright grower that has stood the test of time, remaining a favorite among lilac enthusiasts for generations thanks to its reliable performance, exceptional fragrance, and striking color. It pairs beautifully with softer pink or white flowering shrubs, where its deep jewel tones create a stunning contrast in the landscape.

     

    Highlights:

    • Exceptionally deep wine-red to purple single blooms
    • Beautiful color evolution as blooms mature from deep red-purple to lilac-magenta
    • Large, showy flower clusters with classic, strong lilac fragrance
    • Blooms mid-spring (May)
    • Excellent as a cut flower
