About Tall Blue Wild Indigo
Baptisia australis, commonly known as blue wild indigo or blue false indigo, is a flowering plant in the family Fabaceae (legumes). It is toxic. It is native to much of central and eastern North America and is particularly common in the Midwest, but it has also been introduced well beyond its natural range. Naturally it can be found growing wild at the borders of woods, along streams or in open meadows. It often has difficulty seeding...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.
