mignonette: fragrant insect attractor

I'm very fond of this plant: mignonette

It doesn't look like much, but it smells fantastic and insects are mad for it
I don't know what sub species this one is, but it's in its second season after I brutally hacked it back...

We were gifted a pack of seeds.

I'm trying to figure out where would be the best spot to plant it, or who would be its best guildmates.
