Origin: Introduced by Proven Winners.

Opinion
"
The Spiraea betulifolia is a compact deciduous shrub that would accent a wide rage of planting schemes. This shrub attracts wildlife such as butterflies and is complemented by its hardiness in cold climates and overall stable plant health- making it uniquely valuable. Glow girl, however is not native to Canada and is a much more compact cultivar variety from the original. This shrub works best when massing but its hardiness allows for a wide range planting options. Its yearly interest is one of the selling points for this plant, sprouting bright yellow foliage in spring and is then complemented by showy clusters of white flowers in mid summer holding that until late summer. Autumn brings stunning a array of foliage from colours of orange, to red and even purple.
