Hummingbirds and certain flowers have coevolved together in a mutually beneficial relationship known as mutualism. The hummingbird gets nectar from the flower as a food source, while the flower gets pollinated by the hummingbird. This interdependency helps both species survive. But what specific flowers have this special relationship with hummingbirds? Let’s explore some of the most common mutualistic flowers found in hummingbird habitats.
Trumpet Creeper
The trumpet creeper vine (Campsis radicans) has brilliant orange-red trumpet-shaped flowers that attract hummingbirds. Their curved shape is perfectly adapted to the long, slender beak of a hummingbird. As the bird dips its beak inside for nectar, pollen from the flower’s reproductive organs sticks to the bird’s head and throat. When the hummingbird flies off and visits another trumpet creeper flower, this pollen rubs off and pollinates that plant. Trumpet creepers produce lots of nectar to fuel the high metabolism of hummingbirds. They bloom throughout the summer, providing a reliable food source. Their bright colors stand out as visual cues where hummingbirds can find food.
Fuchsia
Fuchsias are a popular garden plant with drooping flowers in shades of red, purple, and pink. There are over 100 species, many native to tropical regions of North and South America. The flowers have a unique shape with protruding stamens and stigma that are perfectly configured for pollination by hummingbirds. As the bird hovers near the vertical flowers hunting for nectar, its head and throat make contact with these reproductive parts, transferring pollen in the process. Fuchsias produce copious amounts of sugary nectar to attract and nourish hummingbird visitors.
Firecracker Bush
Native to tropical regions, the firecracker bush (Hamelia patens) produces masses of bright red tubular flowers. Their high nectar content makes them a favorite of foraging hummingbirds. As the birds probe the blossoms for food, they pick up yellow pollen on their beaks and heads which then pollinates the next firecracker bush they visit. The shrubs bloom repeatedly throughout the year, providing a reliable food source for resident and migrating hummingbird species. They are commonly grown in gardens to attract hummingbirds.
Salvia
There are over 900 species in the mint family genus Salvia. Many sages and salvias have vividly colored, nectar-rich flowers specially adapted for pollination by hummingbirds. Varieties like pineapple sage, Mexican bush sage, scarlet sage, and Texas sage are popular hummingbird plants. Their tubular flowers perfectly match the long, slim beak of a hummingbird. As the bird feeds on nectar, pollen accumulates on its head and throat then transfers to the next salvias it visits. Hummingbirds rely on the steady nectar supply and sage plants depend on hummingbirds for reproduction.
Snapdragon
Snapdragon flowers (Antirrhinum) come in a rainbow of colors – red, pink, orange, yellow, purple, white. When fully open, the blossoms have a specialized shape with a landing platform for hummingbirds to perch while feeding. The bird’s head goes directly into contact with the flower’s reproductive column while probing for nectar. This allows efficient pollen transfer. Snapdragons produce new flowers continuously through the frost-free season, fueling hummingbirds with a steady supply of food. In return, they get reliably pollinated.
Desert Honeysuckle
Native to the southwestern United States and Mexico, the desert honeysuckle (Anisacanthus thurberi) thrives in arid environments. This hardy shrub blooms in autumn and winter when food is scarce for migrating hummingbirds. The bright red tubular flowers packed with sweet nectar provide essential fuel. The inside of the blossoms are perfectly configured for a hummingbird’s head and beak to pollinate them as it feeds. Desert honeysuckle is a drought-tolerant and low-maintenance addition to gardens in warmer climates.
Lantana
Lantana is a spreading tropical shrub popular in gardens. Its flower clusters come in a mix of reds, oranges, yellows, pinks, and purples. The nectar-rich blooms attract diverse pollinators like butterflies and bees. But hummingbirds frequent lantana the most. Their slender curved beaks and long tongues are adapted to probe the flowers’ tubes and extract the abundant nectar. As they move methodically from bloom to bloom, lantana gets thoroughly pollinated. The plants bloom continuously in warmer climates, providing a steady food source.
Columbine
Columbina flowers have backward curving petals and projecting stamens and pistils that perfectly match the shape of a feeding hummingbird’s head. Inside the blossoms are generous amounts of nectar. When hummingbirds stop to drink it, their head gets thoroughly dusted in pollen. When they move to the next columbine, pollination happens. These spring wildflowers thrive in higher elevations which coincides with hummingbird migrations. Columbines depend entirely on hummingbirds for pollination. In return, they provide essential food after long journeys.
Coral Honeysuckle
This popular garden vining plant has showy flowers in a range of bright colors like orange, red, and yellow. Their long, slender tubes hold plentiful nectar. Hummingbirds love to probe coral honeysuckle flowers with their specialized beaks and tongues. As they move from blossom to blossom feeding on nectar, their heads pick up lobelia pollen which transfers to the next flower. Coral honeysuckle depends completely on hummingbirds for pollination. It blooms repeatedly from spring to fall, providing a constant food source for resident and migratory hummingbirds.
Penstemon
Penstemons are a large group of wildflowers native to North America. They produce colorful tubular flowers in shades of red, pink, purple, blue, and white. Inside the blossoms are generous nectar reserves. Penstemon flowers have just the right shape to match the slender beaks of feeding hummingbirds. As they drink the nectar, pollen covers their heads then transfers to the next penstemon. Over a hundred penstemon species have evolved this exclusive pollination partnership with hummingbirds. In exchange for food, the birds guarantee the plant’s reproduction.
Trees and Vines
In addition to flowers, certain trees and vines have a mutualistic pollination relationship with hummingbirds. Cuphea trees, jacaranda trees, mimosa trees, and silk floss trees all have abundant, hummingbird-friendly blossoms rich in nectar. Among vines, trumpet creeper and trumpet honeysuckle are some of the most popular hummingbird plants. Their vines spread readily on trellises, fences, and arbors, producing masses of red trumpet-shaped flowers full of nectar through the season. As hummingbirds visit for nourishment, they pollinate these plants.
Key Traits of Hummingbird Flowers
Certain floral traits are almost universally present among the many diverse plants that share a mutualistic pollination relationship with hummingbirds:
- Brightly colored petals, often red, that serve as a visual signal to attract hummingbirds
- Tubular or curved blossoms that match the long, slender beak and head of a hummingbird
- Plentiful nectar with 15-25% sugar content to fuel hummingbird metabolism
- Stamens (male parts) and stigma (female parts) located in ideal spots for hummingbird contact and pollen transfer
- Continuous blooming for steady food supply
These specialized adaptations enable the perfect symbiotic relationship between hummingbirds and the flowers they pollinate. The birds get the high-energy food they need, while the plants get effective pollination. Over time, flowers shape themselves to attract and utilize hummingbirds that will reliably pollinate and spread their genetic material. It’s a beautiful example of nature’s harmony at work.
