The Black Knight Butterfly Bush is medium-sized deciduous shrub with pale foliage that can be evergreen in warmer climates (zone 5-9). Summer to Fall Black knight will produce lovely violet-purple conical bloom clusters which are great for attracting butterflies and hummingbirds! After bloom clusters have flowered out, trim the blooms off to encourage additional flowering.
For a seamless planting, plant your Black Knight Butterfly Bush 4 feet apart. For space between plantings, plant them 5-6+ feet apart.
