What are the example of lowland weeds?

Examples of lowland weeds include common species like dandelion (Taraxacum officinale), crabgrass (Digitaria spp.), and thistle (Cirsium spp.). These plants thrive in disturbed soils and can often outcompete cultivated crops for nutrients and space. Other notable lowland weeds include chickweed (Stellaria media) and purslane (Portulaca oleracea), which are commonly found in gardens and agricultural fields. Their adaptability and rapid growth make them prevalent in lowland areas.
