Dark Knight Spirea
Dark Knight spirea is one of the easiest small shrubs to grow in a low water landscape. Throughout spring and early summer, it grows as a compact mound of upright branches covered with grey-green linear leaves. In late summer, dark blue flower spikes cover the shrub.
The flower spikes mature into tan seedheads that persist throughout the winter, capturing snow during winter storms. It can be an excellent, all-purpose, tidy low water shrub.
