Golden Glow butterfly bushes produce ball-like clusters of orangey-yellow flowers that are intensely fragrant. Dense semi-evergreen foliage provides a most striking backdrop to the sprays of clusters that bloom into fall. This hybrid is showy, drought tolerant and attracts bundles of butterflies long after other Buddleias have produced their last blooms. Golden Glow blooms on the previous year’s stems, so limit pruning to dead stems.
