About California manroot
Marah fabaceus, the California manroot or bigroot, is the most common of the manroot species native to California. Its range throughout the state subsumes nearly the entire ranges of all the other California native manroots species and intergrades. Hybrids between California manroot and the other species are common.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.
