Hi there - in Spain and USA coriander is called cilantro so I've always assumed it's the same herb !!!
I've grown coriander from seed for a few years now - best to grow it in situ, with some shade but plenty of warmth for leaf production - harvest leaves regularly and from the top if seed head developing - this encourages leaves from below. Plant readily goes to seed if insufficient water but seeds are a useful spice so a good plant for both leaves and seeds. Interestingly, the leaves and seeds have quite different flavours.
I don't know too much about basil although have both green and purple seedlings at the moment. Have decided to take Monty's advice and plant them in greenhouse with the tomatoes and not outdoors. I think that he said basil requires heat and not too much water.
I also read an article recently about commercial herb plant suppliers who "stroke" their seedlings to encourage them to produce stronger stems - am always willing to give anything a go so am doing this with the basil and other thin stem seedlings - all are doing well but not a scientific experiment so don't know how they would be doing in the absence of "stroking" !!!
I don't know of different varieties of coriander so cannot shed any light Adam Pasco about 'leisure' but would be interested to hear from others as I must say that I prefer the leaves to the seeds
