ARIZONA-SONORA DESERT MUSEUM PLANT CARE INFORMATION Desert Willow or Mimbre Chilopsis linearis DESCRIPTION: Desert willow is not a true willow, but a member of the Catalpa family. It is deciduous and fast growing to 20 feet or more with an equal width. It leafs out in late March or April, soon followed by flowers. The 1” to 2” flowers are usually pale lavender, but can vary from white to maroon (they are consistent on an individual tree). Hummingbirds and butterflies are attracted to the flowers. The leaves are food for the larvae of Rustic Sphinx Moth caterpillars. Desert Willow can be seen in habitat along large washes and permanent watercourses, from Arizona to Texas, and south into Mexico. Some of the many named varieties are: Lois Adams: Flowers are a rich pink-maroon and keeps flowering until the first frost. Produces few seeds. Bubba: Fragrant pink-burgundy flowers in large clusters of flowers towards the tips of the branches which persist from late spring to early fall.Produces few seed pods. Lucretia Hamilton: Intense, deep pink to purple flowers. Smaller than other varieties. Warren JonesTM: Faster growing & holds its leaves longer in the winter. Blooms profusely with showy, light pink flowers during the summer months. Art’s Seedless: large, pink-rose flowers, long narrow bright green leaves; fast growth and no seed pods. ‘Lopur’ Desert Diva™ produces a profusion of dark, purple burgundy flowers. RECOMMENDED USE: It is adapted to desert landscapes, but fits into more intense gardens. Be sure to allow for its ultimate size. CULTURE: Hardiness: Goes deciduous at around 30o F, but is hardy to at least 15o F. Sun tolerance: Full sun or part-day light shade. Watering and feeding: Low to moderate water usage when young. Frequency can be reduced in age, but at the expense of growth and flowering. Deep weekly irrigations when the tree is in leaf encourages the best growth. Feeding is not usually necessary. Soil requirements: Not particular. Pruning: Occasional pruning to shape and remove suckers and watersprouts as needed. .

DESERT WILLOW 'BUBBA' Chilopsis Linearis 'Bubba' Characteristics
DESERT WILLOW ‘BUBBA’ Chilopsis linearis ‘Bubba’ Characteristics Type: Tree Sun: Full sun Zone: 6 to 10 Water: Low to Moderate Height: 25-30 feet Maintenance: Low Spread: 25-30 feet Flower: Showy, Fragrant Bloom Time: Spring through Summer Fruit: Showy Bloom Description: Dark Burgundy and Tolerate: Drought, Dry Soil Pink Texas Native Culture Chilopsis linearis ‘Bubba’ is a vigorous, fast-growing upright selection of desert willow that originated in Texas. Compared to other selections it has a strong vertical form and is less shrubby. It also has glossy, darker green, more lush foliage than other desert willows. It has the capacity to easily grow up to 30 feet tall in the landscape. Starting in late spring and through the summer ‘Bubba’ produces masses of large, fragrant, two-tone burgundy and pink flowers. Like other desert willows ‘Bubba’ is a great choice for full sun, low maintenance, water efficient landscapes. Although it is not seedless, it produces fewer pods than most selections. Each pod containing many winged seeds. Noteworthy Characteristics Chilopsis linearis, commonly known as desert willow, is a large shrub or small multi-trunked tree with a loose open crown. It typically grows to 15-25’ tall with a spread to 10-15’ wide, though some varieties, like ‘Bubba’, grow taller. It is native to gravelly and rocky soils in the Southwestern U.S. and northern Mexico where it is usually found growing in desert grasslands, sandy washes or springs. While the narrow, long leaf shape is indeed willow-like, Chilopsis linearis is in fact related to Catalpa trees, Yellow Bells (Tecoma stans), and Trumpet Vine (Campsis radicans).While oversized in comparison to other members of its family, ‘Bubba’ remains reasonably sized for compact growing spaces as an ornamental accent.

Chilopsis Linearis (Desert Willow)
Chilopsis linearis (Desert Willow) Desert willow is a fast-growing tree reaching up to 25 feet with spectacular trumpet –shaped flowers and glossy green, willow-like foliage. Chilopsis linearis is native to the southwestern United States and northern Mexico, and is commonly seen in dry washes from 1500 to 5000 feet. The fragrant orchid-like flowers in varying colors attract hummingbirds. Desert willow blooms in clusters from May through October. In winter, this tree is deciduous which reveals its interesting branch structure. Desert willow can be planted on western and southern exposures where shade is desired in summer, and allows radiant heat to warm homes or structures in winter. Chilopsis linearis pro- vides light shade for other plants such as Mexican honeysuckle and penstemons. Once estab- lished, this tree can survive on rainfall alone, but supplemental irrigation during the summer will produce more attractive foliage and flowers. Desert willow prefers well drained soil. Its natural form is multi-trunked, but careful pruning will encourage development of a more tree-like form. Desert willow enhances the oasis feeling of a landscape and is a valuable source of food for native wildlife. Because of its leafless nature in the winter, consider grouping evergreen desert trees and shrubs nearby. The many forms of desert willow vary considerably in growth habit, mature height, leaf size, and flower color. Chilopsis can be a tall, upright tree or a weeping shrub. Mature heights range from 18 to 25 feet. The leaves are narrow and lanceolate (lance shaped). Different cultivated varieties of desert willow offer flower colors of white, light pink, lavender, deep purple-red, and royal purple.

Santa Fe National Forest
Chapter 1: Introduction In Ecological and Biological Diversity of National Forests in Region 3 Bruce Vander Lee, Ruth Smith, and Joanna Bate The Nature Conservancy EXECUTIVE SUMMARY We summarized existing regional-scale biological and ecological assessment information from Arizona and New Mexico for use in the development of Forest Plans for the eleven National Forests in USDA Forest Service Region 3 (Region 3). Under the current Planning Rule, Forest Plans are to be strategic documents focusing on ecological, economic, and social sustainability. In addition, Region 3 has identified restoration of the functionality of fire-adapted systems as a central priority to address forest health issues. Assessments were selected for inclusion in this report based on (1) relevance to Forest Planning needs with emphasis on the need to address ecosystem diversity and ecological sustainability, (2) suitability to address restoration of Region 3’s major vegetation systems, and (3) suitability to address ecological conditions at regional scales. We identified five assessments that addressed the distribution and current condition of ecological and biological diversity within Region 3. We summarized each of these assessments to highlight important ecological resources that exist on National Forests in Arizona and New Mexico: • Extent and distribution of potential natural vegetation types in Arizona and New Mexico • Distribution and condition of low-elevation grasslands in Arizona • Distribution of stream reaches with native fish occurrences in Arizona • Species richness and conservation status attributes for all species on National Forests in Arizona and New Mexico • Identification of priority areas for biodiversity conservation from Ecoregional Assessments from Arizona and New Mexico Analyses of available assessments were completed across all management jurisdictions for Arizona and New Mexico, providing a regional context to illustrate the biological and ecological importance of National Forests in Region 3.

Section IV – Guideline for the Texas Priority Species List
Section IV – Guideline for the Texas Priority Species List Associated Tables The Texas Priority Species List……………..733 Introduction For many years the management and conservation of wildlife species has focused on the individual animal or population of interest. Many times, directing research and conservation plans toward individual species also benefits incidental species; sometimes entire ecosystems. Unfortunately, there are times when highly focused research and conservation of particular species can also harm peripheral species and their habitats. Management that is focused on entire habitats or communities would decrease the possibility of harming those incidental species or their habitats. A holistic management approach would potentially allow species within a community to take care of themselves (Savory 1988); however, the study of particular species of concern is still necessary due to the smaller scale at which individuals are studied. Until we understand all of the parts that make up the whole can we then focus more on the habitat management approach to conservation. Species Conservation In terms of species diversity, Texas is considered the second most diverse state in the Union. Texas has the highest number of bird and reptile taxon and is second in number of plants and mammals in the United States (NatureServe 2002). There have been over 600 species of bird that have been identified within the borders of Texas and 184 known species of mammal, including marine species that inhabit Texas’ coastal waters (Schmidly 2004). It is estimated that approximately 29,000 species of insect in Texas take up residence in every conceivable habitat, including rocky outcroppings, pitcher plant bogs, and on individual species of plants (Riley in publication).

The characteristics that set this ‘AZT™’ clone apart from seed selections are the solid-colored, dark purple flowers combined with wider, more upright leaves. ‘AZT™ Desert Amethyst’, like ‘AZT™ Bi-Color’, brings generous shade and much needed summer color to desert landscapes. Arid Zone Trees makes selections from thousands of trees propagated from seed. Only individual trees having the most desirable physical qualities (branching habits, leaf color, leaf canopy, and flower color) and sound horticultural characteristics (rooting, cold hardiness and growth rate) are selected for further study. These trees are then cloned (vegetatively propagated) and planted at our nursery for evaluation. The best of these trees are placed in our cloning production and are designated Variety ‘AZT™’. Since no single selection of any desert tree species is best adapted to all landscape applications, we continually search for new additions to our Variety ‘AZT™’. At first glance the name Desert Willow seems like a contradiction in terms.
