Summer Cascade Kentucky Wisteria brings the romantic allure of wisteria to Northern gardens with dramatically improved cold hardiness that other wisteria species simply can’t match. Long, pendulous clusters of fragrant lavender-purple flowers appear in early summer, creating a cascade of color over arbors, pergolas, and trellises. Unlike Asian wisterias, this well-behaved native selection is less aggressive and often reblooms later in the season for extended interest. Deer and rabbit resistant, cold hardy through Michigan winters, and tolerant of Black Walnut root competition, it’s the wisteria of choice for Great Lakes gardeners who love the look without the worry of tender or rampant species.
