This weed doesn't really do any harm. It grows out of cracks between the paving stones and spreads its multiple branches flat on the surface of the sidewalk. It is soft and filled with fluid so when you cut it liquid oozes out all over your surface. Under the microscope it's like a tour through a funhouse.
