Plant identification request

[mirrorshard]

Does anyone know offhand what this is? Some previous owner or tenant planted it neatly in between the lavender & rosemary, right where I want to put more herbs, and as far as I can tell it's neither use nor ornament. (Obviously I have not attempted to apply the binary edibility test.)

Ah, that's useful, thank you!
