Companion planting

I made a thread on this in organic https://www.rollitup.org/organics/87218-organic-companion-planting.html, but has anyone had any successes (or failures) with using companion plants in outdoor or indoor grows? If not, does anyone know of any other good companion plantds that would be good for pest control, nutrition, yield increase, essential oil/active constituent increase, camouflage, or any other useful trait?

I am trying it now, it's my first grow, though I've been gardening for years.

Coriander (cilantro) repels spider mites and aphids
Yarrow increases oil content in herbs
German Chamomile benefits soil and increases oil production in herbs
Borage contributes to general garden health
Cleome looks very much like marijuana

Excellent. That sounds like a sweet companion setup. I currently only have beans, which contribute nitrogen, but I will soon be planting garlic for spider mites and mint for other insects.
