>herbs in a hot climate?
Me growing in cold climate but here goes: most plants you just have to keep removing the flowers/seed pods, chives, basil, thyme, mint comes to mind among what I'm gowing. Buy varieties adapted to your climate, this needs no more than going to physical store, they will have selected them for you or wouldn't be in business for long. Pic related, use light color pots, or shield them with something it really helps.
