What are your top choices for “sacrificial” plants in the garden? Do you have a surefire, dedicated species or do you use a series of plants based on location, size and usage?

Pictures in order: dill, diakon radish, and london rocket. Adult bullerflies/moths prefer to lay their eggs on the radish greens, while I pluck any caterpillars I find and place them on the dill, where they usually stay. The dill just barely out-paces the caterpillars' hunger.

Periodically, they move to the london rocket that's in direct contact with the dill and very rarely, I'll find damage to mustard greens later in the season and artichoke leaves and catnip earlier in the season. Though, this was before the dill was established.
