Like other pollinators, hummingbirds rely on flowers as a source of food. Considering how much energy they expend beating those tiny wings, the average hummingbird must visit 1000-2000 flowers in a single day. No matter where you live, keep this in mind while considering whether to allow those colorful “weeds” to encroach just a wee bit further into the yard. Every native plant has an important role and wildflower gardens, in particular, contribute so much important food to hummingbirds, bees, and butterflies. Osa Peninsula, Costa Rica.
