The DNR has begun a battle against a gorgeous roadside flower, Purple Loosestrife, that is also "invasive." Loosestrife beetles are coming to our neighborhoods, bred to munch on and kill these tall lovely magenta spikes that bloom in the ditches alongside our scenic roadways, with the hope to eradicate this rejected flowering plant. I believe it when the DNR says that even a pretty flower like this one can be one too many for WI ecology, BUT I feel there is an alien invader that is MUCH, much worse (and far uglier) that is not getting any press at all: TEASEL. You've seen these plants growing in great profusion alongside local highways and the freeway right up to the north side of Milwaukee. These plants are edging north farther each year, possibly due to climate change. To see it in Caledonia, look alongside Hwy.32 near the railroad overpass at Middle Road, where it is abundant south of the overpass, or farther north, an entire pasture of it at a farmette across from the spawling WE energies property. Look for almost colorless green tall spikes with a thistle head, bunched very closely together and speading so as to cover every inch of ground. Once you've identified it, you'll begin to see it everywhere, taking over native weedy plant habitat. Teasel is much worse than the worst of the thistles; its woody thorns make it supremely difficult to handle. I'd like to have the DNR work as hard to eradicate this useless, dangerous plant, as it is working to destroy the lowly and beautiful purple loosestrife. If anyone can make a case to keep and enjoy teasel and let it spread, I'd like to hear it.
