London rocket (Sisymbrium irio)

I saw London rocket for the first time last year (April 2022) in Whitechapel, east London and have been on the look-out ever since. After a suggestion of Tower Hill, I observed it there yesterday (March 2023).

there were some very small plants growing in cracks

plants in the shade were not nearly so developed

some were quite small
