Scilla siberica, sometimes known as Siberian squill, is a small bulb native to southern Russia. It is notable for its ability to grow under black walnut trees, which is useful if you have a black walnut and are looking for things to plant under it. I don’t but I still love this spring ephemeral. It is similar to the related Chionodoxa forbesii but the flowers on that are turned upright while Scilla’s face down. It was getting late in the evening when I took this (6:55 PM) and although the camera was steady (on a bean bag), there was a slight breeze moving the flowers around a little.
