Like all fothergilla, this one is adorned with honey-scented, bottlebrush flowers in early spring before it leafs out. But what sets this outstanding plant apart from the rest is its colorful, silvery blue leaves. In autumn, the blue foliage transforms to shades of rich red, orange and yellow, with multiple shades per leaf in our experience. We have several of these planted here near the barn. 'Blue Shadow' grows fairly slowly, eventually getting 4-6' tall with a spread of 4-5'. Good in sun to part shade. Hardy to Zone 4.
