A few nights after first reading these threads I was bored so opened up a jar of coriander seeds and pushed about 30 into the belfast sink (don't ask) that my wife uses as a 'nursery' for her young plants.
After a few days to my surprise they all sprouted and it was suddenly as though I was a new 'dad' all over again, by the time they got to about 3 inches I found myself with a huge cheesy grin on my face. ;D
Then I went out one morning to find the birds had eaten all but two of them, I am gutted. :-[
Time to buy some pots and compost and grow them indoors methinks.
