Lemon balm (melissa officinalis). It's easy to grow - a bit like mint - and it spreads slowly, but won't take over the world like mint can. The leaves smell beautifully lemony and can be made into tea etc. I think the smell is even better than mint, maybe because it has nostalgic memories for me.
Flowers are kinda boring but the pollinators like them. You can cut it to the ground a few times a year and it will give you a fresh flush of leaves. Fully hardy in the UK - dies down to the ground each winter, but comes back reliably every spring.
I may have just 2 pots, so probably will split one per person (but I'll check in case I have more ready).
