Tiny round buds and vibrant cut-flower-perfect whorled blooms put on a spectacular display, nearly enveloping the fine textured bushy foundation that’s defined by compact upright stems and pewter-green leaves with frosted flip sides. Touted as the best and the bluest of all Caryopteris, ‘Dark Knight’s swank low mounding profile can be staged right up front, tucked next to Rudbeckia ‘Viette’s Little Suzy’ and Achillea ‘Hella Glashoff’ or ushered into smaller gardens.
