When searching for food, hummingbirds visit colorful flowers to sip from the nectar or look for insects on the blooms. Although hummingbirds are often attracted to bright red blooms, they also visit flowers of other colors, including yellow. Gardeners can choose from a variety of yellow flowering hummingbird plants for the home landscape.
Yellow monkeyflower (Mimulus guttatus) grows wild along streams and other moist areas in the western United States. The spreading stems reach up to 12 inches tall. Trumpet-shaped flowers, 1 inch long, appear in the summer among the velvety green leaves. Yellow monkeyflower grows best in USDA hardiness zones 6 to 9. Grow this plant as a cool-weather annual in the southern United States. Plant monkeyflower in partial shade and moist soil and water during dry periods.
The shrub or small tree known as tree tobacco (Nicotiana glauca) grows up to 20 feet tall and 10 feet wide. The upright stems bear bluish-green leaves and tubular yellow flowers in summer and fall. Tree tobacco grows best in zones 10 and 11. Plant tree tobacco in full sun or partial shade. It tolerates some drought but requires water during especially dry periods. The leaves of this tree are poisonous and should not be consumed.
Native to the southwestern United States and Central and South America, Tecoma stans, commonly called yellow bells, reaches up to 25 feet tall. This shrub features clusters of trumpet-shaped flowers from spring through early winter. Frost may cause branches to die back, but the shrub will recover quickly. Plant yellow bells in full sun and well-drained, deep soil in hardiness zones 7 to 11. It tolerates drought but grows best if provided with occasional water.
Four o'clock (Mirabilis jalapa) grows up to 3 feet tall with long, branching stems. Native to Peru, these plants feature dark green, oval leaves and fragrant, trumpet-shaped flowers, 1 to 2 inches long. The flowers typically open in late afternoon. Although four o'clock comes in a variety of colors, the 'Golden Sparkles' and 'Baywatch' cultivars bloom with yellow flowers. Plant four o'clock in full sun in zones 7 to 11. In cooler regions, frost will kill this plant, but in warmer climates it will sprout again from the tuberous roots. It tolerates some drought but benefits from a regular water supply.
The long, hairy stems of Russian hollyhocks can reach up to 9 feet tall. Along the stems, large, funnel-shaped, creamy yellow flowers bloom in spring and summer. Also known as Alcea rugosa, Russian hollyhock resists disease more than other hollyhocks. It grows best in hardiness zones 3 to 8 in full sun and well-drained soil. In particularly hot climates, it prefers partial shade.
