'Grand Cascade' Buddleia Butterfly Bush

Think all Buddleia look the same? Think again! Unlike the typical Butterfly Bush, the panicles on this flowering shrub cascade downward, similar to the look of a weeping willow or a bridal wreath spirea. Light lavender purple flower panicles are enormous at 12-14" long and 4" thick. They're nearly the size of your head!

    Since they frequently die all the way back to the ground in northern winters, it is best to cut back all of the old wood to about 12" in the spring. Doing so will result in more compact plants. They will quickly grow back to their normal height by fall and will flower just as prolifically in late summer since they bloom on new wood. You may notice that the flowers tend to be longer and deeper colored in cooler weather.
