Welcome to the Desert Legume Program (DELEP) Discover the mission of DELEP, a program committed to preserving legume biodiversity from arid and semi-arid regions around the globe. Exciting Update: The Desert Legume Program is now proudly administered by Boyce Thompson Arboretum! This program, previously a partnership between the University of Arizona and BTA, made a significant transition in summer 2024 when its invaluable seedbank, the heart of DELEP, relocated to Boyce Thompson Arboretum. For seed requests or inquiries, contact us directly at [email protected]. Join us in protecting and celebrating legume biodiversity!
About the Desert Legume Program (DELEP): Preserving Global Legume Biodiversity
The Desert Legume Program (DELEP) is dedicated to preserving the biodiversity of Fabaceae (Leguminosae), the third-largest family of vascular plants, with a strong presence in the floras of arid and semi-arid regions. Despite their significance, wild legumes from dry regions remain understudied in terms of their economic potential.
Legumes are second only to cereal grains in their importance to humanity, serving a wide array of purposes:
- Food crops and forage crops
- Green manure for sustainable agriculture
- Forestry and erosion control
- Sources of medicines and industrial compounds
- Shade, shelter, and landscape plants
Many legumes possess a unique ability to convert atmospheric nitrogen into a plant-usable form through symbiosis with specialized bacteria, making them vital for ecological health and sustainable farming practices.
DELEP Mission
- Seed Conservation: Acquire and preserve seeds of legumes native to the arid and semi-arid lands of the world.
- Research: Advance knowledge of the nature and utility of these species.
- Distribution: Share germplasm with professionals and individuals who have a legitimate interest.
- Conservation: Support desert legume biodiversity through in situ and ex situ preservation methods.

Collecting and directing stormwater is essential for a desert garden`s survival. If left unmanaged, pooling rain can damage plants and nearby buildings. Thanks to the generous support of Water Wise Arboretum donors, we now have several stormwater features around the Smith Greenhouses! It helps protect our historic buildings and guides the water to plants that need it most.
You can spot one of these water capture systems in front of the Smith Greenhouses. Arizona poppies are currently blooming inside, a living proof of its success!

The vibrant color on this caterpillar is a warning sign to any predators: do not eat!
The Pipevine Swallowtail feeds on Pipevine plants as larvae. Because Pipevine leaves are toxic to many animals, consuming them makes the caterpillars toxic as well. Their eating habits make the perfect defense mechanism!

The coatis are back!
This family of coatis has recently been spotted exploring the Canyon Region. We`re happy to report that in all our observations of them, they seem happy, healthy, and safe.
As a reminder, if you see coatis (or any wildlife) on the trails, keep a distance of at least 50 feet and refrain from giving them any food. They have plenty of delicious snacks growing right here at the Arboretum. By respecting their space, we can ensure safety for the coati, humans and pets enjoying nature.
And of course - if you take any photos, don`t forget to tag us so we can see them!

There`s nothing quite like walking through our hummingbird garden on a quiet summer morning. Flowers are in bloom, butterflies flutter across your path, and hummingbirds stop to sip nectar from nearby firecracker plants. It feels like walking through a magical portal that leads you deeper into the Arboretum.
When you visit us next, we hope you pause to really take in your surroundings. Observe the plant life growing around you and notice how the wildlife interacts with it. See what flowers are in bloom and notice their vibrant color. Let your curiosity guide you to the next wonder of the garden.
