The garden plant is found throughout the country.
It is a neophyte, which was introduced into England in the 1750s
and first noted in the wild in the 1910s.
It grows in waste places and in the cracks of pavements and
at the base of walls.
It varies from being a casual to fully naturalised. I have seen it
growing in the same place at the base of a wall over 5 years.
