The Nanho Blue Butterfly Bush is a medium-sized deciduous shrub that can be evergreen in warmer climates (zone 7-9). Summer to fall, Nanho Blue will produce lovely lavender-blue conical bloom clusters which are great for attracting butterflies and hummingbirds! After a cluster of blooms has flowered out, trim the blooms off to encourage additional flowering.
For a seamless planting, space your Nanho Blue Buddleia Butterfly Bush 3-4 feet apart from plant center to plant center. For space between plantings, plant them 4+ feet apart.
