Coriandrum sativum Coriander DD I
This is an East Mediterranean introduction or casual which can arrive as a birdseed alien or these days, as an escape from gardens where the owners just must have the freshest Coriander to follow Nigella's recipes. This one was only slightly aromatic but the crushed seeds smelled very strongly indeed. The outer petals of the flowers are much larger than the rest and it was this that made me realise I was looking at an umbellifer which I don't usually see.
C. sativum has escaped mostly into England and quitye often in the south east. It is only rarely recorded in Wales, Scotland and Ireland.
