I have a shrub at THO that has busted out in pink blooms this year. It turns out that this nice little plant is an invasive species… a native of Siberia (and other parts of Asia). A weed that was brought here as an ornamental plant but it pushes out the native varieties.
My first reaction was to stop and admire it… now I know what it is and am not so sure it is pretty.
