mystery plant identification

Asked July 27, 2019, 10:06 AM EDT

When these "volunteers" started early in the season, I thought they were snapdragons and left them alone. Now closing in on close to 7 feet and with tiny, fuzzy blooms, it's clear they're not snapdragons! Are they (hopefully) native and beneficial, or should I be killing them with abandon?

This plant is Horseweed and should be pulled before it goes to seed and spreads, Hope this helps
