Nursery Hours:
Planting season in the Coachella Valley has wrapped up, and we’re closed until October! However, we’re still available by appointment through April for our High Desert clients and those outside the valley.

Like the creosote, the Smoketree is an integral part of the Coachella Valley landscape. You’ll most often find it in sandy desert washes or along roadsides where the sand is disturbed. Though native to the Mojave as well, its range is limited to specific locations. This is a plant that demands excellent drainage and will not tolerate heavy or compacted soils.
Smoketree is a spiny, almost leafless perennial legume tree that grows to about 20 feet tall, with an irregular form and open canopy. It often challenges our traditional image of a “tree.” Its foliage is aromatic and its stems are densely covered with fine, whitish hairs, giving it a silvery-gray appearance—hence the name “Smoketree.” In early summer, the tree bursts into bloom with vivid violet to indigo-blue flowers, creating a dramatic contrast to its usual muted color.
Flowers appear in lateral clusters in June and are followed by small-seeded pea pods. The tree's deep taproot makes it extremely drought tolerant once established, surviving on rainfall alone, but also difficult to transplant. It is well-adapted to the hot, dry conditions of southern California, Arizona, Baja California, and is also common in Joshua Tree National Park.
Smoketree flowers are highly attractive to a wide variety of pollinators including native bees, honeybees, butterflies, moths, flies, and even hummingbirds. Its seeds may be eaten by small mammals and granivorous birds, making it a valuable habitat and food source for desert wildlife.
Growing Plants in the Desert — Important Information
The information presented here is, to the best of my knowledge, accurate and based on my research from reliable sources, observations I have made of plants growing in my, and other gardens I have visited, and observations of the plants in their native habitats. I would appreciate your feedback and experience to help me educate others!
Cacti: In my experience, cacti are much happier in the filtered shade here in the low desert of the Coachella Valley. Colors are more vibrant and they bloom more profusely, especially the non-native varieties. If you pay attention to how our native barrel and beavertail opuntia grow in the wild, it is frequently tucked in the rocks under creosote or another shrub.
Light Requirements: I have found that in our desert (Sonoran/Colorado) “full sun” plants can take and appreciate the late afternoon filtered sun, especially in the hot summer months.
