About Creosote Bush
Larrea tridentata is known as creosote bush and greasewood as a plant, chaparral as a medicinal herb, and as gobernadora in Mexico, Spanish for "governess", due to its ability to secure more water by inhibiting the growth of nearby plants. In Sonora, it is more commonly called hediondilla....From Wikipedia via iNaturalist — article, CC BY-SA.

Photography tips
- Photograph flowers on calm, overcast mornings to avoid wind blur and harsh shadows.
- Get low: a shallow depth of field (f/2.8–f/5.6) isolates a bloom against soft color.
- Stay on trails — trampling meadows kills plants and ruins next year's display.
- Try a kaleidoscope abstract of a single bloom with our online kaleidoscope tool.
