What Kind of Flowers Attract Hummingbirds and Why Do They Prefer Vibrant Colors?

Hummingbirds are fascinating creatures, known for their incredible speed, agility, and vibrant plumage. One of the most intriguing aspects of these tiny birds is their attraction to certain types of flowers. But what kind of flowers attract hummingbirds, and why do they seem to prefer those with vibrant colors? This article delves into the relationship between hummingbirds and flowers, exploring the characteristics that make certain blooms irresistible to these avian wonders.
The Science Behind Hummingbird Attraction
Hummingbirds are primarily nectarivores, meaning they feed on the nectar produced by flowers. This nectar is a rich source of energy, providing the birds with the calories they need to sustain their high metabolism. However, not all flowers are created equal in the eyes of a hummingbird. The birds are particularly drawn to flowers that offer a high sugar concentration in their nectar, typically around 20-25%. This concentration provides the optimal balance of energy and hydration.
Flower Characteristics That Attract Hummingbirds
-
Color: Hummingbirds are highly visual creatures, and they are particularly attracted to bright, vibrant colors. Red, orange, and pink flowers are especially appealing to them. These colors stand out against the green foliage, making it easier for the birds to locate the flowers from a distance. Interestingly, hummingbirds can see colors in the ultraviolet spectrum, which is invisible to humans. This ability allows them to detect patterns on flowers that guide them to the nectar.
-
Shape: The shape of a flower also plays a crucial role in attracting hummingbirds. Tubular or trumpet-shaped flowers are particularly well-suited to the birds’ long, slender beaks and tongues. These shapes allow the hummingbirds to access the nectar efficiently, while also providing a perch for the birds to rest on while feeding.
-
Nectar Production: Flowers that produce a large amount of nectar are more likely to attract hummingbirds. The birds have a high energy demand, and they need to feed frequently to maintain their metabolism. Flowers that offer a generous supply of nectar are more likely to be visited repeatedly by hummingbirds.
-
Bloom Time: Hummingbirds are migratory birds, and their presence in a particular area is often seasonal. Flowers that bloom during the hummingbirds’ migration periods are more likely to attract them. For example, in North America, hummingbirds are most active during the spring and summer months, so flowers that bloom during this time are more likely to be visited.
-
Fragrance: While hummingbirds are primarily attracted to visual cues, some flowers also produce fragrances that can attract the birds. However, the role of fragrance in hummingbird attraction is less well understood than that of color and shape.
Popular Flowers That Attract Hummingbirds
-
Trumpet Vine (Campsis radicans): This vigorous climber produces large, trumpet-shaped flowers in shades of orange and red. The flowers are rich in nectar, making them a favorite of hummingbirds.
-
Bee Balm (Monarda didyma): Also known as bergamot, this perennial plant produces clusters of tubular flowers in shades of red, pink, and purple. The flowers are highly attractive to hummingbirds and other pollinators.
-
Cardinal Flower (Lobelia cardinalis): This striking perennial produces tall spikes of bright red flowers. The tubular shape of the flowers is perfect for hummingbirds, and the plant is often found in moist, shaded areas.
-
Salvia (Salvia spp.): There are many species of salvia, and most of them produce tubular flowers that are highly attractive to hummingbirds. The flowers come in a range of colors, including red, pink, purple, and blue.
-
Fuchsia (Fuchsia spp.): These elegant plants produce pendulous flowers in shades of pink, purple, and red. The flowers are rich in nectar and are a favorite of hummingbirds.
The Role of Hummingbirds in Pollination
While hummingbirds are primarily interested in the nectar that flowers provide, their feeding behavior also plays a crucial role in pollination. As the birds move from flower to flower, they inadvertently transfer pollen from one bloom to another, facilitating the process of fertilization. This mutualistic relationship benefits both the hummingbirds and the plants, as the birds get a reliable food source, and the plants get help with reproduction.
Creating a Hummingbird-Friendly Garden
If you want to attract hummingbirds to your garden, there are several steps you can take:
-
Plant a Variety of Flowers: To attract hummingbirds, it’s important to plant a variety of flowers that bloom at different times throughout the year. This ensures that there is always a food source available for the birds.
-
Choose the Right Colors: As mentioned earlier, hummingbirds are particularly attracted to bright, vibrant colors. Red, orange, and pink flowers are especially effective at attracting these birds.
-
Provide a Water Source: Hummingbirds need water for drinking and bathing. A shallow birdbath or a dripping water feature can be a great addition to your garden.
-
Avoid Pesticides: Pesticides can be harmful to hummingbirds and other pollinators. If possible, avoid using chemical pesticides in your garden.
-
Provide Shelter: Hummingbirds need places to rest and hide from predators. Planting shrubs and trees can provide the birds with the shelter they need.
Conclusion
Hummingbirds are remarkable creatures, and their attraction to certain types of flowers is a fascinating aspect of their behavior. By understanding the characteristics that make flowers attractive to hummingbirds, you can create a garden that not only benefits these birds but also enhances the beauty of your outdoor space. Whether you’re a seasoned gardener or a novice, planting hummingbird-friendly flowers is a rewarding way to connect with nature and support these incredible birds.

Additionally, many red flowers produce nectar with a high sugar concentration, which is ideal for the birds’ high energy needs.
Q: Can hummingbirds see colors that humans can’t?
A: Yes, hummingbirds can see colors in the ultraviolet spectrum, which is invisible to humans. This ability allows them to detect patterns on flowers that guide them to the nectar.
Q: How often do hummingbirds need to feed?
A: Hummingbirds have a very high metabolism and need to feed frequently to maintain their energy levels. They may visit hundreds of flowers each day, consuming up to half their body weight in nectar.
Q: What other animals are attracted to hummingbird-friendly flowers?
A: In addition to hummingbirds, many other pollinators, such as bees, butterflies, and moths, are attracted to hummingbird-friendly flowers. These flowers provide a valuable food source for a wide range of wildlife.
Q: Can I attract hummingbirds to my garden if I live in an urban area?
A: Yes, you can attract hummingbirds to your garden even if you live in an urban area. Planting a variety of hummingbird-friendly flowers, providing a water source, and avoiding pesticides can help create a welcoming environment for these birds.
