Scientific profile
Allium cepa is an introduced, established terrestrial herbaceous plant in Great Britain. It has broad, non-woody leaves and typically attains a height of about 0.5 m. Originating from parts of Asia and Africa, it has been recorded in cultivation and as an escape in Europe since at least 1500. The plant favours sunny positions, moderately moist, nutrient-rich, neutral to weakly acidic soils, and warm conditions. It forms arbuscular mycorrhizal associations. Flowering takes place from June to August, providing a low supply of nectar and pollen (each rated 1 on a relative scale).
