Do you like the blooms? If so, keep them until they need to be cut back. If not, remove them. It's as you wish. I grow a variety that doesn't bloom, although I do enjoy the ones that do.

The bloom is fairly small and pale. I have seen several
situations where the color is picked up by a larger flower in
the pinky-purple range and the combination is very pretty, especially with the soft silver lambs ear leaves. I can't remember now what the companions were.

I think they have quite a pretty colored bloom and leave mine on as the bees seem to like them. I always intend to deadhead them but there are always a lot of bees around them so don't. Really, it's just as easy to pull the seedlings as to deadhead.
