The reward for us is the arrival of comely creatures encourage people to to our gardens; the reward for wildlife is that they continue to find places to live, even in our growing cities. create desert-friendly For more than 25 years Tucson Botanical Gardens has been gardens that support educating the public on the special relationships between gardening and the desert. Although situated in the very center of a wildlife and make up large metropolitan area, the Gardens has attracted more than 90 species of birds and 40 species of butterflies to its diverse grounds. for lost habitat. In 2002 the Gardens received a leadership grant from the Institute of Museum and Library Services for a project called "Desert Connections." With these funds, and in partnership with Tucson­ Pima Public Libraries, we initiated a series of lectures about conservation through gardening with wildflowers and gardening to attract birds and butterflies. An extensive database and this cover photos: gardeners' guide were also important components of the project. lg, JPB sm, GKA A complete table of the best bird and butterfly plants for the art NMC Tucson area is available at www.desertconnections.org.

Seasons summer Summer is really two seasons: a dry "fore-summer" (May - June) and a summer rainy season (July- September), which ushers in occasional to frequent afternoon thunderstorms. Both seasons are hot, with high temperatures ranging from the mid-90s to low 100s.

fall (late September - early November) Fall months are typically warm to hot with cool nights. The first frost may arrive in early November, but this is not easy to predict. Many late-season flowers bloom during the warm days of fall, and this is the ideal time period for planting a variety of species. Soils Tucson's soils are alkaline and range winter (late November - February) Winter climate varies from cold, from rocky in the foothills areas to wet storms accompanied by freezes, to balmy periods with days in the sandy or day-laden in the valley. ?Os.

Do not use water from kitchen sinks or toilets. new plants: With their limited root systems, new plantings need to be carefully watered several times a week, or more frequently in hot, dry weather. Thoroughly soak the root ball and the soil around it, so new roots can push into the soil easily. Frequency of watering may also depend on how windy it is, because wind hastens evaporation.

maturing plants: Root systems take one to two years to become established. As plants mature, you may water less often, but you may need to water more deeply to create a reservoir for roots to draw upon-for trees, up to two feet in depth. As trees and shrubs get larger, you should increase the circumference of the area watered. During the heat of summer, watering schedules for established landscapes might look like this: very low (once a month or less): established cactus, ocotillo, agave, yucca low (every 2 - 4 weeks): desert trees and shrubs moderate (every 1 - 2 weeks): vines, groundcovers, small shrubs high (more than once a week): containers, herbs, veggies, seasonal flowers, roses, and other non-desert adapted plants The frequency of watering may be cut nearly in half with cooler weather. Cacti and succulents generally do not need water in winter, except from the rain.

Sun In the Southwest, sunshine plays a particularly significant role in planning and caring for your garden. Many potted plants and delicate succulents appreciate filtered light under airy desert trees or ramadas covered with vines or shade cloth. western exposures are hot in the afternoon. Use tough plants that can take the heat. Watering may need to be frequent. eastern exposures get full sun in the morning and relief from sun in the afternoon. A wide variety of plants thrive here. southern exposures receive sun all day, even in winter. Plants that adore sunlight thrive in southern exposures. South-facing walls are the best places for cold-tender plants. northern exposures do not get sun in the winter. North-facing walls are mainly useful for summer plantings, where they are likely to receive sun for a good part of the day.

During the cooling days of fall, the golden flowers Doug Danforth, of mountain marigold and rabbitbrush extend the bloom. 70 Common Butterflies ofthe Southwest Butterflies are closely tied to the plants on which their caterpillars, or larvae, feed. These are called larval foodplants. Southern Dogface use daleas; Empress Leilias use desert hackberry; Leda Ministreak caterpillars feed on mesquite;

Swallowtail Giant Swallowtails use citrus plants; and the caterpillars of Black Swallowtails feed on parsley and rue. It's easy to integrate caterpillar foodplants into existing landscapes as background plants, shade trees, colorful accents, and herbs.

For a truly effective butterfly garden, a tolerance for holey leaves is recommended. Caterpillars rarely do any permanent damage.
