This is a European introduction which easily naturalises itself once it finds a suitable habitat. In this part of London it was quite common. It is a hybrid between Euphorbia waldsteinii (Waldstein's Spurge) and Euphorbia esula agg. The distribution is concentrated on the south east of England with only a little in the north and none in Scotland, Ireland and very little in Wales.
