This is an 'unwinding' plant. Notice how the best flowers are always at the top of the stem? The first flowers were the bottom ones, when they were at the top. As they are pollinated they close up. The plant keeps unwinding so that the new flowers are well postioned for best visibility. New buds are growing in the wound up section at the top. When they're ready the plant will unwind some more. I suppose it does look like the neck of a fiddle. Grows in great abundance. There are many species of Fiddleneck, the most common is Amsinckia intermedia   (Forget-Me-Not family)
