Recommendation gravel strip

Hello! I'm after recommendations. I've got a very narrow strip of gravel at the edge of some decking. The neighbours fence replacement was a slimmer construction so I gained a couple of inches.
Any recommendations for little plants that seed in gravel (like Erigeron would), but the catch being partial shade? Only a few hours of sun a day om that strip.

I'm sure herb-robert will move itself in. But any suggestions welcome. Searching the Internet isn't quite getting me to an answer.

Thank you
