Hummingbirds

Ruby-throated hummingbirds, our only nesting hummingbird species, are most attracted to nectar-rich plants having bright red or orange blossoms of tubular shape. You will have to choose your plants carefully - many of the popular, nonnative landscape plants are unsuitable for nectar-seekers.

Stick with flowering natives as much as possible, especially trees, shrubs, vines and perennials, which will require a minimum of care. Annuals, on the other hand, must be replaced each year. Single-flowered blossoms have more nectar than double ones, so avoid double-flowered and sterile hybrids.

Hummingbirds feed most comfortably from blossoms two feet or higher above the ground. They will also visit hanging potted plants and sugar-water feeders on open patios and porches. Be sure to consider the best viewing opportunities your windows and porches afford as you place your hummingbird garden or plants. Remember, too, that flowering plants nearly always require full sun.

Artificial feeders: use with caution

The safest, most balanced way to encourage hummingbirds is to provide their favorite nectaring blossoms in sunny habitats. But, as most hummer fans know, sugar-water feeders are usually a sure draw for these birds. If you choose to supplement the birds' natural diet in this way, protect them from hazardous, spoiled solutions by observing the following safety tips:

• DO use a feeding solution of four parts water to one part white granulated sugar - no stronger. Bring water to a full boil, dissolve in sugar and promptly cool. Refrigerate unused portions.
• DO choose feeders that can be dismantled and thoroughly cleaned to remove bacteria and fungus molds. Scrub with hot water and vinegar (no soap) every four or five days.
• DO NOT use honey. It may contain botulism toxins and fungi fatal to hummingbirds.
• IT IS NOT necessary to use colored solutions when using red-colored plastic feeders.
• DO NOT use insect sprays to control bees, wasps or ants on feeders. Vegetable oil applied around the feeder openings and on the suspending wire should discourage these unwanted visitors. Many commercially available feeders come equipped with plastic bee guards.

Hummingbird gardens

An excellent planting design for a hummingbird garden follows the wildlife landscaping principle of layered vegetation. Build a cascade of plant attractants by securing a trellis to a wall and covering it with trumpet creeper or coral honeysuckle vines. Or consider a red buckeye (north Florida) or geiger tree (south Florida) for height at the back of your hummingbird garden. Add lower shrubs such as coral bean or fire bush, and then low flowering annuals and perennials closest to the ground.
