Fast Facts
- Famous nurse-plant: its shade and leaf litter create microclimates that facilitate seedling establishment (notably saguaros and other cacti).
- Mass spring flowers provide abundant nectar/pollen for bees and tons of food for seed-eating insects and rodents.
- Sparse canopy and green stems perform photosynthesis year-round, providing shade and structural habitat across the landscape.
