I have a yellow evening primrose, and not knowing how to prune it, I have cut it all down to ground level. Is this correct, and if not, will it survive?

Yes, this should be fine. Most people cut back the evening primrose after it finishes flowering (you can also remove the spent blooms to promote re-blooming) by cutting away any crowded stems and pruning back the to base level in fall.
