Herbaceous or not, pinch out everything if you want the very best out if your plants. It is about grwing a god rot system first and foremost. Every plant I grow is grown to be as good as it can be. I have experimented with the Chelsea chop before it became fashionable, I pinched out some and left others unpinched, I planted out when small and grew others on by repotting, I compared mpc with John Innes, you name it and I have tried it. One factor though persuaded me never to plant out small stuff in summer or autumn..viz., that they get "lost" or overwhelmed by weed, pest or conditions.
Orchid lady, we all do things our own way. Try, experiment and compare. Growing plants is not rocket science.....we have all learned to grow in a way that works for us. You will too.
Finally, why plant out something that merely occupies a small space whilst growing? Better to look at an annual filling that or bigger space with colour or scent whilst your small perennial is quietly growing away in a pot perhaps out of sight.
