About Blue Pigroot
Sisyrinchium micranthum, commonly known as blue pigroot or striped rush-leaf, is a grass-like species in the iris family, Iridaceae. It is native to Mexico, Central America, and South America and widely naturalised elsewhere. The white to cream flowers are between 10 and 20 mm in diameter and have blue to purple centres. These are followed by rounded 3 to 8 mm brown capsules that enclose the dark brown seeds.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.
