Description: Myagrum perfoliatum is an annual herb that can grow up to 1 m. tall. The leaves are broad, giving them the distinct look of clubs, and they form rosettes that can reach 45 cm in diameter. The leaves are waxy, blue-green and hairless, and the leaves do not have leaf stems (petioles). They are clasping leaves. The stems are erect, blue-green, waxy and very branched. Flowers are pale yellow, 2-4 mm in diameter with four petals. The flowers are clustered. Pods are hard, wedge shaped 5-7 mm long and 4-5 mm wide. History: Biology & Spread: Bird’s eye cress thrives on alkaline clay soils, and spreads rapidly through productive agricultural lands. It can compete strongly with crops because of the rosette base. Seeds are thought to last up to 10 years in the soil. Heavily-infested paddocks can have up to 3000 seeds per square meter. Ecological Threat: Myagrum perfoliatum considered a serious weed of broadleaf crops such as chickpeas, canola, lupins, faba beans, field peas and lentils. Bird’s eye cress is considered a potential seed contaminant. It can create blockages during harvest. It competes with agricultural crops, reducing crop yields up to 50%. US Habitat: Grows best on alkaline clay soils and often found in agricultural areas. Distribution
Resembles/Alternatives: The rosette leaves can have Myagrum perfoliatum resemble Rapistrum rugosum (bastard cabbage), Sonchus oleraceus, Lactuca serriola, Lactuca saligna Management: Since Bird’s eye cress is tolerant to many commonly-used herbicides, control in agricultural crops is difficult. Also, the plant undergoes germination from April - October so seeds re-establish pre or post emergent herbicide treatment.
