Oxybasis urbica

Scientific profile

Oxybasis urbica belongs to the family Amaranthaceae. It is an archaeophyte, meaning it was introduced to Britain and is now established. The plant typically grows in full sun on moderately moist, nutrient-rich soils that are often calcareous or at least basic. It shows a slight tolerance of salinity and is associated with habitats subject to low disturbance severity. Records from central Europe indicate occurrences in arable land, old vineyards and railway sidings, and in Britain it occupies similar nutrient-rich, disturbed but relatively stable sites. Its strong light requirement (Ellenberg indicator value 7) reflects its need for open, unshaded situations. Flowering takes place from June to September.
