Calibrachoa, commonly known as Million Bells, is a popular ornamental plant valued for its prolific, cascading blooms that last from spring until the first frost. Gardeners frequently choose this low-maintenance plant for hanging baskets and containers due to its continuous display of color. Many people who cultivate these vibrant flowers also hope to attract hummingbirds, those tiny, energetic visitors known for their rapid wingbeats. Understanding the relationship between this garden annual and the feeding habits of hummingbirds helps enthusiasts create a more effective habitat.
The Calibrachoa and Hummingbird Connection
Calibrachoa attracts hummingbirds due to the physical characteristics of its flowers, which align closely with the birds’ feeding needs. The blossoms have a tubular or trumpet-like shape, perfectly suited for the hummingbird’s long bill and tongue to access nectar deep within the corolla. Hummingbirds are highly responsive to vibrant colors, particularly shades of red, orange, and pink. Calibrachoa varieties in warmer tones, such as bright red or magenta, are especially effective at drawing attention from a distance. While the nectar concentration in a single flower may be lower than in some dedicated hummingbird plants, the plant’s sheer abundance of continuous blooms provides a consistent and reliable food source throughout the growing season.
Optimizing Garden Placement for Feeding
To maximize Calibrachoa’s effectiveness, gardeners should focus on planting arrangements that capitalize on the hummingbird’s visual cues and feeding preferences. Hummingbirds are attracted to large patches of color, so grouping several plants together in a mass planting creates a more visible and appealing target than scattering single plants. Planting in elevated containers or hanging baskets is also advantageous, as hummingbirds often prefer to feed a few feet off the ground for safety and better visibility.
Calibrachoa performs best in full sun, requiring at least six hours of direct sunlight daily for optimal bloom production. Adequate sun guarantees a continuous supply of flowers and places the food source in an open, brightly lit area where hummingbirds feel comfortable feeding. Maintaining consistent bloom quantity requires regular fertilization throughout the season, which supports the plant’s high energy demand and ensures a steady nectar flow for the birds.
Complementary Elements for Habitat Creation
While Calibrachoa provides nectar, a complete hummingbird habitat requires supplementary elements to support all aspects of the birds’ lives. Offering a sugar-water feeder can supplement the floral nectar, especially during periods of low bloom production. The standard mixture for this artificial nectar is a ratio of one part white granulated sugar to four parts water, and it is important to avoid using red dyes or honey, which can be harmful.
A complete habitat should also include:
- Feeders must be cleaned frequently, ideally twice a week in hot weather, to prevent the growth of mold or bacteria.
- If placing multiple feeders, space them at least 15 to 30 feet apart, since hummingbirds are highly territorial.
- Provide a source of water, such as a fine misting device or a slow dripper, which hummingbirds prefer for bathing and preening over traditional deep bird baths.
- Nearby trees, shrubs, or dead branches should be available to serve as safe perches for resting and surveying their territory.
