It is a native plant to Europe and now spread worldwide, with white to pink, funnel-shaped flowers with yellow stamens in the center.

11. Johnsongrass (Sorghum halepense)

Perhaps, you may mistake the Johnsongrass with Nutsedge as their physical features are similar. However, they are different. This perennial grass has emerging branching stems with white ribs.
