Caryopteris 'Dark Knight'
In late summer and early fall, when few other shrubs are in bloom, Caryopteris ‘Dark Knight’ is a showy bloomer. Its deep blue to lavender flowers are very interesting against the gray-green foliage. Beautiful in front of low walls, in mass groupings, as a hedge, or even as a specimen plant, it has a tidy, upright growth habit. It is small enough for a patio garden. Grows to approximately 3’ x 5’.
