Once More with Enthusiasm

GM2  GM1

The invasive garlic mustard has just about finished flowering, and fruits and seeds are developing. But we still have a little time before they mature and dry fruits scatter seeds by the thousands.  Garlic mustard, imported because it is edible, marches straight into the woods and displaces natives such as spring beauty, wild ginger, trilliums, bloodroot, and, of course, its relatives the toothworts. Three species of butterflies, which lay eggs on the toothworts, are affected because garlic mustard is toxic to their larvae. Entire plants  usually come out of the ground fairly easily, given a gentle tug. And every plant pulled  means thousands of seeds not dispersed.
