Horseweed is a tall plant that grows in fields and along roadsides. It has small, fluffy flowers that look like little daisies and can be found in many places during the summer.
Habitat: Grasslands
The horseweed is a tall, slender plant with an unbranched stem covered in many narrow, hairy leaves that spiral upwards. Its tiny, whitish-green flowers grow in clusters at the very top, giving it a somewhat scruffy, upright appearance.
