Flatspine Bur Ragweed

Flatspine Bur Ragweed is a pesky plant that goes by many names including Annual Burweed, Annual Bursage, Hooker's Bur Ragweed, and Western Sand-Bur. Ragweed is considered a seasonal allergy because it peaks at different times of the year. It produces an abundance of pollen that is very lightweight and travels easily through the air. This widespread pollen is also responsible for “hay fever” and allergic asthma, and triggers nasal allergies in both people and pups.
