ELI5: When there has been no rain & all the plants you want to keep around are dying, why do weeds thrive? Could we not "breed" that hardiness into our flowers & such?

For the plants that matter, like ones we eat, that kind of hardiness usually works against large yields. We need plants to perform very well and grow quickly to feed all of us. Weeds survive because they don't grow juicy fruit, or large edible roots. They just devote their all to... weedlike growth.
