Hummingbirds are drawn to colorful, native flowering plants that have no scent, such as bladder pod, hummingbird sage, serpentine columbine, and Vine Hill manzanita, but more than simply plants, hummingbirds need habitat that includes shelter, shade, and water. Flowering weeds, such as milk thistle blooms, provide a soft lining for hummingbird nests, and spider webs are the glue that holds the nest together; leaving some of each will increase the chances of receiving humming visitors.
