The Desert Willow, known botanically as Chilopsis linearis, is a small, deciduous tree prized for its remarkable hardiness and striking, trumpet-shaped flowers. Despite its common name, it is not a true willow but a member of the Bignoniaceae family, making it highly drought-tolerant once established. Its ability to flourish in arid climates and produce vibrant blooms from late spring through fall makes it a popular choice for xeriscape and native plant gardens. The search for this southwestern native begins by identifying reliable sources that offer quality specimens and specific cultivars.
Finding Local and Regional Sources
Acquiring a Desert Willow often starts with local retail options, especially for buyers located within the tree’s native range across the southwestern United States. General garden centers and large home improvement stores may stock young plants during the primary spring planting season. However, these sources often carry seed-grown stock, which can result in significant variation in flower color and overall tree form.
A better option involves seeking out regional nurseries that specialize in native or drought-tolerant plants. These specialized vendors are more likely to offer named cultivars, which are propagated from cuttings to ensure predictable traits like specific flower color, such as the deep magenta ‘Lucretia Hamilton’ or the white ‘White Storm’. Consulting with local agricultural extension offices or native plant societies can provide a list of reputable regional growers who stock high-quality Chilopsis linearis.
Purchasing Online and Specialized Growers
For buyers outside the Desert Willow’s native habitat or those seeking a specific, hard-to-find cultivar, remote acquisition through online retailers is a common pathway. Specialized desert plant nurseries or mail-order catalogs often ship small potted trees or bare-root stock directly to the customer. When purchasing online, confirm the supplier’s shipping policies, including any guarantees concerning plant health upon arrival.
The form of the tree received depends on the vendor, ranging from seeds and small starter plugs to one-gallon container plants. While seeds are the most economical option, they will produce genetically variable trees and require several years to reach flowering size. Bare-root trees or small potted cultivars grown from cuttings offer the most direct path to a mature, predictable specimen.
Selecting a Healthy Specimen
Regardless of the source, a careful inspection of the specimen is necessary before finalizing the purchase. Begin by assessing the overall canopy for signs of vigor, looking for vibrant green foliage without yellowing or spotting, which could indicate nutrient deficiency or disease. The branches should appear sturdy and well-developed, with no evidence of broken limbs or significant pest infestation, such as webbing from spider mites or clusters of aphids on new growth.
A thorough check of the root system is important for container-grown Desert Willows. Gently remove the tree from its pot and examine the root ball; healthy roots should be firm, white, or light tan, and spread outwards. Avoid plants that are severely pot-bound, indicated by thick roots circling tightly around the perimeter of the soil. Circling roots will struggle to establish properly after planting and can ultimately choke the tree.
Post-Purchase Preparation and Timing
The timing of the purchase and planting is a factor in successful establishment for Chilopsis linearis. In warmer climates (USDA Zones 7 to 10), planting is best done in the fall, allowing the roots to establish through the cooler, wetter months before the stress of the summer heat. For gardeners in colder regions (Zones 5 and 6), planting in the early spring is recommended to give the tree an entire growing season to establish its root system before winter dormancy.
Once acquired, the Desert Willow should be given a period of temporary acclimation, especially if it is arriving from a different climate or a protected greenhouse environment. Place the container in a location with partial sun and shelter from harsh winds for a few days before planting. During this transitional phase, ensure the root ball remains consistently moist but not waterlogged, providing a deep watering whenever the top few inches of soil feel dry to the touch.
