Asclepias_syriaca_-_Common_Milkweed
To contribute to the Milkweed Flower Photo Project on iNaturalist, upload a photo of either the common (Asclepias syriaca) or the showy (A. speciosa) milkweed. We will use your photo and the GPS coordinates in the meta data of your photo to track how flower shape and color change across the US. Photos uploaded to iNaturalist will also be distributed on the Global Biodiversity Information Facility (GBIF) where other scientists around the world can use them to make important discoveries.
