Native flowers attract bees and offer pollen + nectar for them :)
Don’t forget that honeybees aren’t the only bees nor the only pollinators. Ask your local university or beekeepers / native plants association about what you can do to help out in your area!
Even worse, honeybees can compete with wild local bees… Best solution is indeed flowers (local plants are usually better choices) and providing a good environment for wild pollinators
