Galinsoga quadriradiata aka Hairy Galinsoga

Galinsoga quadriradiata, also known as shaggy soldier, Peruvian daisy, and hairy galinsoga, is a species of flowering plant in the Asteraceae family. It is native to central Mexico but has become naturalized in many other parts of the world, including North and South America, Europe, Japan, the Philippines, northern India, and Nepal. This invasive summer annual weed has an erect or sprawling stem that can grow up to 2 feet tall. Its leaves, which are green and egg-shaped, have stems of their own and stick out from the main stem. During growth, the leaves appear smaller and are covered in tiny hairs. The plant produces small flower heads with 4 to 5 white ray flowers that have yellow discs. If left to its own devices, hairy galinsoga can spread quickly over large areas and is commonly found in meadows, naturalized areas, ditch banks, open fields, and lawn areas.
