Amethyst Falls Wisteria is a cultivar of the American wisteria (Wisteria frutescens) known for its graceful, fragrant racemes of lavender-purple flowers, its less-aggressive growth compared to the classic Asian wisterias, and its suitability for smaller gardens or trained structures.
It offers a lovely vertical and cascading feature—ideal for arbors, trellises, fences or even as a trained small tree form.
