Insanely invasive and on its way to seven feet tall, this … thing is all over UD‘s garden.
Note that it has begun to put out small daisy-like flowers.
UPDATE: Aska Gardener informs me it’s a weed, and a nasty one. They can’t precisely identify it, but they are familiar with it, and it must be destroyed. So this morning, with the ground still wet from storms, UD lifted, roots and all, every stalk of mystery weed she could find. ANOTHER UPDATE: I think it’s an evil variety of goldenrod.
