About Stinknet
Oncosiphon pilulifer (often spelled piluliferum) is a flowering plant in the daisy family (Asteraceae) native to southern Africa. It is known as globe chamomile and sometimes stinknet due to its strong, unpleasant odor. It is a species of "least concern" (low conservation concern) in South Africa and considered invasive in some parts of North America.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.
