could the lemon stuff be lemon balm? It is lovely,but very invasive if let to go to seed.Or it could be lemon verbena?All my herb books are packed away,but lemon balm should be fine in pots.Chives do well in containers too & sage.
Lemon balm IS invasive but on the other hand, it's easy to pull up by the roots. Mine pops up all over the place, including in cracks in the path, but I don't really mind - it's lovely stuff, makes a great herbal tea, which is supposed to be good for getting rid of headaches.
Trim it back when it flowers so that it doesn't go to seed (ie cut off the tops), and keep pulling up roots that spread beyond the boundary you want it to have. If you think its spreading habit is really going to bother you, you could keep it confined to a pot sunk into the ground, as you're advised to do with mint.
Good luck with all of them - my faves, apart from lemon balm, are sage, rosemary, chives and borage (pretty blue flowers, v easy to grow from seed). Basil doesn't seem to like me too much so far, but I intend to keep trying.
I just pick off a handful of leaves from the top(not too much stalk), wash them, stick them in a teapot and pour boiling water on. Drink after about four minutes. It may be an acquired taste if you're not used to herbal teas at all (my sister didn't think much of it, but she never drinks herbal tea), but if you are used to that kind of tea, then I imagine you'll like it.
top tip for those buying the overpriced basil in tesco's (turnupthebass!)....
buy one pot of overpriced basil (usually less than a packet of basil seeds). Take out of pot and gently seperate EACH stalk. Plant in an individual pot, remembering, particularly with basil, to nip out the growing centres on a regular basis. More than 80% of mine always flourish into full and bushy plants this way.
The reason for this is the stuff you buy at the supermarket is just a pot full of forced seedlings... seperate them and they will flourish!
