AI-generated description

Lepidium bonariense, also known as Argentine peppercress or South American pepperwort, is an annual herb native to South America. In Qatar, it has been reported as a naturalized weed, often found in coastal areas, roadsides, and disturbed habitats. It grows up to 30-50 cm tall, with branching stems, small white flowers, and pungent-tasting leaves. Studies in Qatar have noted its presence in various regions, including Doha and the northern coast, where it thrives in saline soils and can tolerate high temperatures.
