what to grow at the base of fig tree?

Couldn't find any info on the internet on wether it is ok to plant things around the base of my fig tree? It is a young tree. I have a bunch of lavender plants i want to move out of one area, would their root systems be too deep? What about hair's tale grass? Cornflowers?

thanks

I vote for nothing. I like to keep my figs clear, so that suckers can sprout and it looks more like a bush than a tree.  If you do that, you have an endless supply of new starts to use to propagate more bushes (trees).  Figs aren't really conducive to a good understory.

fair enough, i only have the one in the ground and intend to pick up several more at a seed exchange but i think i'll keep the newbies in big pots for now. I am not even sure the one survived the winter, thanks for the advice though!
