London rocket
London rocket, Sisymbrium irio, is a herbal plant in the family Brassicaceae. It is an annual herb exceeding three feet in height with open, slender stem branches. The flowers are small with four pale yellow petals. The basal leaves are broad and often lobed, while the upper leaves are linear in shape and up to four inches long. The fruit is a long narrow cylindrical silique which stays green when ripe. The younger pods overtop the flowers. When dried the fruit has small red oblong seeds.[+]
Sisymbrium irio, also known as London rocket, is an annual herb native to Europe and Western Asia. In Qatar, it has been naturalized and can be found growing in disturbed areas, roadsides, and waste grounds. It typically blooms from February to May, producing small yellow flowers. The plant's presence in Qatar indicates its adaptability to arid environments and ability to thrive in areas with human disturbance.

London rocket (Sisymbrium irio) on Green Circles (center-pivot irrigation) in Irkhaya (Irkaya) Farms. Qatar, February 20, 2015Salwa Road, QatarLondon rocket (Sisymbrium irio) was observed growing on Green Circles, which are center-pivot irrigation areas, in Irkhaya Farms in south-western Qatar. On March 29, 2014, the plant was spotted in this region, indicating its ability to thrive in irrigated agricultural areas. A year later, on February 20, 2015, it was again observed in the same location, suggesting that it has adapted well to the local environment and can persist over time. The presence of London rocket in these areas highlights its capacity to colonize and grow in cultivated fields with sufficient water supply. This plant species appears to be tolerant of the irrigation practices used in Qatar's agricultural fields. Its growth in these areas may indicate a potential for it to become a weed species in irrigated crops.
