Hummingbirds are attracted to flowers that are red, orange, or purple. These colors are visible to hummingbirds from a distance, and the flowers often have a long, tubular shape that makes it easy for hummingbirds to reach the nectar inside. Some of the most popular flowers that attract hummingbirds include bee balm, columbine, foxglove, impatiens, nasturtium, petunia, salvia, and zinnia.
In addition to their bright colors, hummingbird-attracting flowers also typically produce a lot of nectar. Nectar is a sugary liquid that hummingbirds use for energy. The more nectar a flower produces, the more attractive it will be to hummingbirds.
