I have been trying to grow some Coriender for a while now without much
success ............. mainly because it goes to seed as quickly as it
grows .......... I then discovered that I needed a 'for leaf' variety
such as Centrillo (or a something similar name)

These seeds seem like rocking horse manure, and our local garden
center look all glassy eyed when I mention 'leaf variety' but sure
enough produced a packet with ' CORIANDER FOR LEAF' stamped all over
the packet .................. these went to seed even quicker than the
others !!!

I am planting in grade one silt soil (just to make everyone else
envious, normally we just throw stuff in the ground - no matter - and
it will grow, the soil is that fertile :-) )

Or could this be the problem?? I know parsley likes rubbish soil
