Coriander (cilantro) readily goes to flowering and seeding; however, in the US there are cultivars with names such as "Slo-bolt" (Johnny's Sel. Seeds) reputed to be slower to bolt.

I grow nine kinds of basil. All will start flowering early if stressed by climatic or watering extremes. I try to start them off well and pinch terminals starting when the plants are small so as to increase branching. I find the flavor of annual basils (Genovese, Neopolitino, Monstuoso, the various reds, and the licorice to be best at flowering. The perennials tend to be much stronger-flavored and seem to want to drop leaves as they go into flowering. But this last observation is preliminary. I am in my second year of side-by-side trials.
