On our way out to walk the dogs this morning, I noticed that the echinopsis “Easter Lily” cactus flower was open. I grabbed the camera and got a picture while I could. By late morning, the flower had wilted. There are several more flower buds on the cactus, so I will be alert to get pictures of them as they open.
According to Wikipedia, echinopsis species are native to South America (Argentina, Chile, Bolivia, Peru, Brazil, Ecuador, Paraguay and Uruguay). They grow only in situations where the soil is sandy or gravelly, or on the sides of hills in the crevices of rocks. Apparently, they are OK in Arizona too, Click on the image to enlarge.
