Floral color communicates to pollinators. Pollination is, after all, the priority of all flowers. Those that rely on pollinators more than breezes for pollination must therefore advertise. They effectively customize their bloom for preferable pollinators. Some incorporate floral fragrance if necessary. Most preferable pollinators are insects. Some are hummingbirds.

Seven species of hummingbird inhabit California. Some are always here. Some migrate south for winter. A few are only here while they migrate between farther south and farther north. All eat only small insects and floral nectar. Blooms which rely on hummingbirds for pollination are happy to provide. They have a mutually beneficial symbiotic relationship.

Many plant species have customized their bloom for pollination by hummingbirds. Many of these flowers are elongated, tubular and curved to fit the long beaks of hummingbirds. Most, although not all, are bright and rich colors that hummingbirds prefer. Bright red and orange are probably their favorite colors. Floral fragrances are more for other pollinators.

Many who enjoy gardening enjoy hummingbirds within their gardens. Hummingbirds are as colorful as some small flowers, but are much more dynamic. They enjoy hummingbird feeders and birdbaths or simple saucers of water. They also appreciate the various sorts of flowers that appeal specifically to them. Such flowers can appeal to everyone anyway.

Hummingbirds enjoy too many flowers to list. Those that customize their blooms for them will be expecting them. Many that customize their blooms for other pollinators can attract them anyway. Zinnia, coneflower and most composite flowers are ideal for pollination by bees. Many of their bright floral colors that attract bees entice hummingbirds incidentally.

Columbine and nasturtium are more customized for hummingbirds. Penstemon, foxglove and various trumpet vines accommodate a range of pollinators. Honeysuckle, lupine and sages do too, but seem to fit thin hummingbird beaks best. Bright floral color of hibiscus, fuchsia, canna and bottlebrush are impossible to ignore. Indiscriminate taste is an asset.
