As they are a meadow plant that grows in grassy land just let it do its thing. If it's in a pot, perhaps put the pot in the soil in a quiet place, but don't forget it, pop a label in the edge of the pot

With luck they will self-seed and you will get an even larger clump as the years go on.

I collected seed from one of mine last year and now have a little forest of seedlings in pots.
