Weird Garlicky smelling weed
I've been gardening for a few decades now and never saw a weed like this before. It showed up about 5 years ago and despite ripping it out where ever I saw it, it's now in every area of the garden. It grows about 2-3' and blooms with little white flowers in clusters, sort of like wild phlox. It has a very strong garlic odor when pulled. Can anyone tell me what this is and how I can get rid of it? Thanks. BTW - Anyone know if there an online encyclopedia of weeds with pics.
