By the way about growing anise hyssop from seed: I got a packet from somewhere like Johnny's a few years ago. The seeds are tiny, almost dustlike, and in my desert climate I had a lot of trouble getting them started without them just getting roasted off by the sun. Once I finally got some started with some careful shading and unshading, they have grown, stayed perennial in some places, and self-seeded successfully. The leaves make a nice herbal tea, and in particular when soaked in boiling hot water and left to cool, makes a very sweet and delicious iced tea.
About lemon balm by seed, I had a packet of seeds and never got even one germination, but when I got a chunk of root from a friend, it did fine. I had it in a container for a year or two and it never really thrived there, but once I got it in the ground (in my greenhouse) it has really grown, and this year for the first time flowered. It's mainly known as a tea herb, but I've been chopping it fine and mixing into salads, thinking it might make little bursts of lemon-scent in the salad.
Although they are both in the mint family, and lemon balm looks a lot like mint, they supposedly don't spread by runners, but I've seen mentioned that they can self-seed and go weedy. I haven't found that to be a problem (yet).
