Hi there! A friend of mine is trying to ID this spring flower which is naturalized with siberian squill in her lawn. She lives in central NC. The plant grows from small bulbs or corms and has squill-like leaves. The flowers are about 1" across. What has me stumped is the triangular structure in the center of the flower-- I have never seen anything like that. The flower reminds me of six or seven different plants, but is not any of them.
