Amaranthus hybridus, also known as smooth pigweed or green amaranth, is an annual herb native to the Americas but widely naturalized in many parts of the world, including Qatar. In Qatar, it has been found growing in various environments, often as a weed in agricultural fields, along roadsides, and in other disturbed areas. The plant can thrive in a variety of conditions, showcasing its adaptability. Its presence in Qatar highlights the global distribution and resilience of invasive species.
Observations of Amaranthus hybridus in Qatar were made at various locations, including Al Doha Al Jadeeda and Onaiza areas in Doha, as well as Irkhaya Farms. The plant was found growing on streets, median strips, and in irrigated farms. It was observed at different times of the year, from March to May, with seedlings emerging in April. The plants were often large and produced red flowers. Multiple observations were made on Al Istiqlal Street in Onaiza area, where the plant grew abundantly on the median strip. The species was also found in Green Circles (center-pivot irrigation) in Irkhaya Farms, suggesting its ability to thrive in different environments. Overall, Amaranthus hybridus appears to be a common and adaptable species in Qatar. Its growth patterns and abundance were consistently observed across different locations and times.
