Hi, this summer’s heat prevented me from maintaining my house garden. When it was finally cool enough to tend, I found these unfamiliar tall weeds growing along my house, ranging from 3 feet tall to over 5 feet. I’ve tried every weed identification site online but haven’t found a match. They are tall, with narrow loose saw edged leaves and topped with seed buds, when open they have fluffy white “flowers”. Since I don’t know these weeds, I’d like more information, such as, do I need long sleeves in addition to gloves to pull them out? If so, will give me a rash? Do I need a mask over my nose? I’m not highly allergic but don’t want to mess around something I don’t know.
