Rare. There is a good population on a stock-brick wall, Rivington Road, Buile Hill (SJ7999). Plants also occurred on brick-rubble in a parking area opposite the Duke of York Ale House, Eccles (SJ7798, 1991-1992) but did not persist.
Note the historic record just outside of the Salford Borough for Chaddock Lane, Boothstown (SD7100, J Evans, Grindon 1859). It is possible that plants may still occur on walls about Boothstown.
