Gaura out of control!

I have a variety of gauras but they are sprawling out or five feet along the ground.
Should I have pruned them right down in the spring or is that what they do?
What would happen if I cut them back now?

    You'd lose all the flowers and maybe the plant.   I cut mine back to the crown in March when I see the new growth starting.   One was sprawly in habit for a couple of years so I put supports around it - like a peony cage support - but this year it's got the idea and is growing more upright.

    I didn't cut mine back and they have flopped all over the place but I don't have the heart to cut back when they're flowering. Still, I will know better next year.

    Lesson learnt. Thank you @Obelixx. Same with penstemons cowardly pruning. 
    They stayed in leaf all this winter. Do I still wait until spring to remove current stems?

    I would but you could also try shortening them so they don't lose all their leaves and flowers and have a shock..

    maybe trim some of the stems back to 6 inches to see if you get a flush of new growth

    I might try a few and hope they don't notice.

    I cut back the most vigorous one back to about a foot soon after the last post ( cue bugle and flag). It has sprouted all along the stems and I think there may be flower buds in the ends😊
    That was the bog standard white one. Now I'm going to go for the dark flowered one and the one with the variegated leaves. At least I know it's not going to kill them

    Update: Masses of flower buds after a few weeks. Don't  be shy. Prune it!
