Ambrosia artemisiifolia
Common ragweed is a tall plant with green, jagged leaves and tiny green flowers. It grows in many places and is known for its ability to spread quickly in gardens and fields.
生息地: Urban areas
The common ragweed has fern-like, deeply lobed leaves that are hairy and grey-green, often lighter underneath. Its inconspicuous greenish-yellow flowers grow in slender spikes at the top of the plant and branch tips. This makes it look less showy than many other plants blooming in late summer.
